AX: In isolated tree mode, an ignored replaced element contributes a
character to the string for a range
https://bugs.webkit.org/show_bug.cgi?id=324639
rdar://187887711
Reviewed by Chris Fleizach.
An ignored replaced element, an <img alt=""> say, added an object replacement
character to the
string for a text marker range spanning it. The main thread emits nothing for
one, as does
auxiliaryTextForObject, which has a comment mentioning that unignored replaced
elements
contribute one U+FFFC, and ignored ones contribute nothing.
The element's text run holds that character regardless, so a text marker can
address the element.
forEachTextPiece emitted every run's text verbatim and so leaked it. Skip the
run text of an ignored
replaced element, leaving the run itself alone.
