For XHTML documents, resolve named character entities (e.g., )
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
:heading() now matches based on a computed heading level, which is based
on the level of the tag (h1, h2, etc) and then modified by these two new
attributes.
I'm caching this heading level on HTMLHeadingElement, based on the dom
tree version. That's more invalidation than is actually needed, but it
saves us calculating it over and over when the document hasn't changed.
The failing test cases are:
- Implicit headingreset for modal dialogs which is apparently unspecced
and controversial.
- Not walking the flat tree properly. A flat tree ancestor of a
slot-assigned element is its slot, which is something we don't do
anywhere that I could find. I've made a note to look into this later.
We also don't implement the `ReflectRange` IDL attribute yet, which
means we're not clamping the read value of `headingOffset`.

Introduce the HTMLSelectedContentElement and integrate it into
<select>, <option> and HTMLParser.
See whatwg/html#10548.
There are two bugs with WPT tests which causes the third subtest
in selectedcontent.html and selectedcontent-mutations.html fail.
See whatwg/html#11882, web-platform-tests/wpt#55849.
- Rename HTMLOptionElement's `owner_select_element()` to
`nearest_select_element()` to better match spec terminology.
- Update HTMLSelectElement's option list related algorithms.
This change is part of the customizable <select> spec work.
See whatwg/html#10548.
Previously, validation_message() always returned a hardcoded "Invalid
form" string, now it correctly returns the custom validity error
message when the element is suffering from a custom error.
Other validation errors still return the "Invalid form" message.
This implements parsing part of customizable <select> spec update.
See whatwg/html PR #10548.
Two failing subtests in `html5lib_innerHTML_tests_innerHTML_1.html`
and `customizable-select/select-parsing.html` are due to the spec
still disallowing `<input>` inside `<select>`, even though Chrome
has already implemented this behavoir (see whatwg/html#11288).

As we now have a field in that dictionary, I removed the separate
`source` parameter from ToggleEvent::create(). Also updated the
relevant test.
In this case, we should just draw a line from the last point in the
path to the start point. Previously, a division by zero caused nothing
to be drawn.
