AX: InheritedFrameState needs to be sent to remote frames via IPC
https://bugs.webkit.org/show_bug.cgi?id=306578
rdar://169222211
Reviewed by Tyler Wilcock.
This PR adds the IPC messages to send InheritedFrameState between frame hosts
and remote
frames. This allows frames in different processes to respect aria-hidden,
visibility, and
inert state from their hosting process.
Some special things need to happen here instead of just sending through the
IPC. When we
receive the message, `recomputeIsIgnoredForDescendants` needs to be called in
order for
the frames tree to update appropriately. Also important is that we start
initializing
AccessibilityScrollViews with RemoteFrames with a m_frameOwnerElement, so that
isHostingFrameRenderHidden can be computed properly.
New testing infrastructure (to come) will allow us to test this via layout
tests.
