AX iOS: Accessibility search should surface out-of-process iframes as remote
element placeholders
https://bugs.webkit.org/show_bug.cgi?id=316040
rdar://178471548
Reviewed by Chris Fleizach.
When VoiceOver navigates by rotor (e.g. headings) on iOS, the in-process
accessibility
search run by AXSearchManager silently dropped any out-of-process
(site-isolated) iframe
it crossed, so content inside cross-origin iframes was unreachable by rotor.
Now, rather than skipping a remote frame, the search records it in tree order
and returns
its AXRemoteElement platform placeholder inline. VoiceOver descends into that
placeholder
to reach the iframe's content.
The obsolete -[WebAccessibilityObjectWrapper
_accessibilityShouldUseCustomRotor] hook (which
disabled the custom rotor under site isolation) is removed.
