Log Message:
-----------
Confirming an IME composition can remove its containing positioned element
https://bugs.webkit.org/show_bug.cgi?id=321674
Reviewed by Ryosuke Niwa.
When confirming a composition, WebKit deletes the pending composition
text before inserting the finalized text. WebKit also deletes selected
text when starting a recomposition.
These deletions used the normal selection deletion behavior, which may
expand the selection to include a containing special element. Since
positioned elements are treated as special elements, this could remove
the element containing the composition and reinsert its text into a
styled span.
Disable special-element expansion when deleting composition text,
including pending composition text and text selected for recomposition.
Normal user-initiated selection deletion behavior remains unchanged.
