Tabs opened from links on AppKit can be created before their URL is
loaded. That left background open-url tabs with the location field as
their stored responder, so switching to them later restored address-bar
focus instead of web content focus.
Track each tab's preferred responder, restore it when AppKit makes
the tab key, and mark page-backed open-url tabs to prefer the web view.
Blank new-tab pages still keep the location field focused.
Teach LibWebView autocomplete to query HistoryStore before falling back
to remote engines and move the wiring out of the AppKit frontend.
Refine matching so scheme and www. boilerplate do not dominate results,
short title and substring queries stay quiet, and history tracing can
explain what the ranking code is doing.
When an element is fullscreened, we now hide the application menu and
location bar. The user can hover over the top of the window to make
them show. When fullscreen is requested for the application directly
from the UI, we do not hide the location bar. This matches Safari's
behavior.
This lets us avoid each UI needing to handle link clicks directly, and
lets actions stored in LibWebView avoid awkwardly going through the link
click callbacks to open URLs.
By migrating the debug menu to LibWebView, the AppKit and Qt UIs are now
in sync - the AppKit UI was previously missing some actions.
Further, this inadvertently fixes bugs around applying debug settings to
new web views, especially across site-isolated processes. We were
previously not applying settings appropriately; this now "just works" in
the LibWebView infra.
This migrates all duplicated context menus from the UIs to LibWebView.
The context menu actions are now largely handled directly in LibWebView,
with some UI-specific callbacks added to display e.g. confirmation
dialogs.
Actions that only ever apply to a specific web view are stored on the
ViewImplementation itself. Actions that need to be dynamically applied
to the active web view are stored on the Application.
This removes the old autoplay allowlist file in favor of the new site
setting. We still support the command-line flag to enable autoplay
globally, as this is needed for WPT.
