REGRESSION (Safari 26): Missing paint invalidation of area previously covered
by a repositioned element
https://bugs.webkit.org/show_bug.cgi?id=299728
<rdar://problem/161570899>
Reviewed by Simon Fraser.
This change ensures that when the parent layer
- has full-repaint bit set
- but does necessarily enclose this 'destroyRoot' renderer (out-of-flow box
does not contribute to the size of the parent layer)
we still manage to invalidate the area by issuing a forced repaint.
