4e48ba36bd LibWeb: Better handling of union types in IDL code generation
First check if a string is a member of the enum before attempting
numeric conversion. This generates correct code for fields like:

AudioContextOptions {
  latencyHint: AudioContextLatencyCategory | double;
}

35839af2d2 LibWeb: Optimize getComputedStyle() to avoid layout when possible
Previously, getComputedStyle() would always call update_layout() for
most properties. This was expensive since layout involves a full tree
traversal even when only style information is needed.

This change introduces a more granular approach:
- Properties needing layout computation (used values like width/height)
  still call update_layout()
- Properties needing a layout node for resolved value computation
  (colors, border widths, etc.) also call update_layout()
- All other properties now only call update_style()

The set of properties needing layout node for resolution is now defined
in Properties.json via the "needs-layout-node-for-resolved-value" flag,
rather than being hardcoded. This is generated into a new function
property_needs_layout_node_for_resolved_value().

3b90eb1d49 LibWeb: Recompute child style when parent's display changes
When a parent element's display property changes (e.g., to flex or
grid), children may need to be blockified or un-blockified.
Previously, children only received a recompute_inherited_style() call
which doesn't run the blockification logic.

This patch adds a parent_display_changed flag to the recursive style
update that forces children to get a full style recompute when their
parent's display change triggers a layout tree rebuild.

5fc276872a LibWeb: Add style invalidation for :open pseudo-class
Add proper style invalidation when the `open` attribute changes on
HTMLDetailsElement and HTMLDialogElement. The :open pseudo-class can
affect sibling selectors (e.g., `dialog:open + sibling`), so we need
full subtree + sibling invalidation.

acd38ad795 Tests/LibWeb: Implement action_sequence in testdriver-vendor.js
This implements WebDriver Actions API support for key sequences with
modifier tracking in our testdriver-vendor.js. The action_sequence
function processes key sources, tracks Shift/Ctrl/Alt/Meta state across
events, and dispatches keys with the appropriate modifiers via
Internals.sendText().

This allows us to pass WPT tests that make use of that API in our own
test-web runner.

746362e5de LibWeb: Handle WebDriver special keys and Mod_Keypad in keyboard events
Add webdriver_key_to_key_code() in Internals.cpp to properly translate
WebDriver special key codes (0xE000-0xE05D) to KeyCode values with
appropriate modifiers. This ensures keys like Enter, Backspace, and
arrow keys are handled correctly when sent via Internals::send_text().

In EventHandler::handle_keydown(), strip Mod_Keypad when determining
Enter key behavior since it only indicates key location (numpad vs
standard keyboard), not a behavior change. The modifier is still passed
through to KeyboardEvent for the location property.

This gains us 656 WPT subtest passes in `editing`.

instead of a <br> element. Use <br> only for padding at end of line to

c6fab541b7 LibWeb: Fix storage set broadcast event never broadcasting old value
We had skipped some steps in the spec and were:
 * Always broadcasting an old value of null, instead of what it
   actually was previously.
 * Still broadcasting a storage event even if the value had
   not changed in storage compared to the last value.

Fix both issues by returning what the old value is in the setter and
implementing the missing logic.

bf77aeb3dc Tests/LibWeb: Support WPT variant meta tags in test-web
Add support for WPT test variants, which allow a single test file to be
run multiple times with different URL query parameters. Tests declare
variants using `<meta name="variant" content="?param=value">` tags.

When test-web encounters a test with variants, it expands that test into
multiple runs, each with its own expectation file using the naming
convention `testname@variant.txt` (e.g., `test@run_type=uri.txt`).

Implementation details:
- WebContent observes variant meta tags and communicates them to the
  test runner via a new `did_receive_test_variant_metadata` IPC call
- test-web dynamically expands tests with variants during execution,
  waking idle views after each test completion to pick up new work
- Use index-based test tracking to avoid dangling references when the
  test vector grows during variant expansion
- Introduce TestRunContext to group test run state, and store a static
  pointer to it for signal handler access

This enables proper testing of WPT tests that use variants, such as the
html5lib parsing tests (which test uri, write, and write_single modes)
and the editing/bold tests (which split across multiple ranges).

6ce312e22f LibRegex: Prevent empty matches in optional quantifiers

are satisfied, empty matches should not be considered for further
repetitions. This was not being enforced for optional quantifiers
like `?`, so we had extra capture group matches.

fe2bc2bfe7 LibWeb: Improve scrollingElement handling
This change is currently entirely undetectable because of what the
added FIXME talks about. Currently, the HTML element's overflow is
always set to visible in both axes, so it getting set to "clip" in
the imported test ends up not mattering at all.

668d3afde0 LibWeb: Properly parse attributes for CSS-connected FontFace
Previously we would just set the attributes to the serialized
descriptors, even if they were the empty string.

We now apply defaults when we have empty descriptors and apply parsing
logic from the various `set_*` methods (only applicable to `font-family`
so far where we now extract the value from either a string or a
custom-ident)

Fixes an issue in some css/css-shapes WPT tests where we weren't
properly matching fonts.

d4c2b69c8b LibWeb: Avoid void elements when inserting text
This seems to be a spec issue for the `insertText` editing command.
Other browsers behave as if the cursor is put just before the void
element, so we copy that. For inline void elements, we find the first
equivalent point which effectively traverses into the preceding inline
node.

535d2476a7 LibRegex: Implement proper lookbehind via new StepBack opcodes
This introduces a new mechanism for evaluating lookbehind assertions by
adding four new bytecode opcodes: SetStepBack, IncStepBack,
CheckStepBack, and CheckSavedPosition.

These opcodes replace the previous GoBack-based approach and enables
correct handling of variable-length lookbehind patterns,
where the match length cannot be known statically.

Track lookbehind greediness in the parser and propagate it to bytecode
generation. Allow controlled backtracking in lookbehind bodies while
avoiding incorrect captures during step-back execution.

Partially fix issue: #3459

1b41659efd LibXML+LibWeb: Use existing HTML entities table for XML parsing too
For XHTML documents, resolve named character entities (e.g., &nbsp;)
using the HTML entity table via a getEntity SAX callback. This avoids
parsing a large embedded DTD on every document and matches the approach
used by Blink and WebKit.

This also removes the now-unused DTD infrastructure:

- Remove resolve_external_resource callback from Parser::Options
- Remove resolve_xml_resource() function and its ~60KB embedded DTD
- Remove all call sites passing the unused callback
