Reviewed by Tyler Wilcock.
AX clients like VoiceOver may request the AttributedString of a TextMarkerRange
using the WebArea object. Since we don't cache the AttributedString for the
WebArea, this causes a hit to the main thread. Furthermore, since the
TextMarkerRange for a given object is created off the main thread and expects
to be accessed off the main thread, it may not return the correct
AttributedString when used on the main thread. This change ensures that the
cached AttributedString for a given object is returned even when it is
requested using the WebArea or any other object instead the object that owns
the range.
