AX: Accessibility layout tests can dirty style at invalid times via JS
notification handlers, causing incorrect behavior and asserts
https://bugs.webkit.org/show_bug.cgi?id=309087
rdar://171643206
Reviewed by Joshua Hoffman.
accessibility/focus-in-remote-frame.html was marked as Skip because it
occasionally dirtied style in the middle
contexts that expected clean style (namely
AXObjectCache::performDeferredCacheUpdate). Fix this by reposting
focused-change notifications to layout tests asynchronously, allowing
performDeferredCacheUpdate to complete
without dirtying style in the middle.
Also make accessibility/focus-in-remote-frame.html less likely to trigger this
issue by forcing clean style and layout
immediately after dirtying it.
