AX: aria-relevant="text" not handled properly when setting/replacing text
https://bugs.webkit.org/show_bug.cgi?id=312958
rdar://165656891
Reviewed by Tyler Wilcock.
When text is replaced/set using APIs like innerText/textContent, the node can
get regenerated, leading
to a new accessibility object being created. This causes those nodes to be
considered "additions". In
the previous logic, that meant those elements wouldn't be announced for
aria-relevant=text regions.
The fix for this is to consider additions that are text content to be text
changes. If aria-relevant=
additions, this supersedes this and includes all content.
