REGRESSION (258819@main): Wolfram Alpha dropdown box has repaint artifacts
https://bugs.webkit.org/show_bug.cgi?id=251816
<rdar://104966985>
Reviewed by Antti Koivisto.
Due to eager display content invalidation, repaints issued after calling
RenderBlockFlow::invalidateLineLayoutPath produce empty rects.
Normally this invalidation call is followed by a layout which will eventually
issue another repaint. This second repaint, with no partial layout support in
IFC (and most content are now covered by IFC)
we will most likely be a full, though redundant repaint.
(note that this newly introduced repaint may be overly inflated when tall
container has constantly changing short inline content)
