Percent-width blocks cannot form a re-layout boundary
https://bugs.webkit.org/show_bug.cgi?id=247913
rdar://102577429
Reviewed by Alan Baradlay.
This patch is to align Webkit behavior with Blink / Chromium and Gecko /
Firefox.
Inspired by (+ Tests):
https://chromium.googlesource.com/chromium/src.git/+/da179e152dff0ab3e3dabc72299bd4fb586881c9
A block with non-visible overflow can only form a re-layout boundary if both
width and height are fixed.
The block may be inside a shrink-to-fit container (there's no cheap and
reliable way to detect that), so that changes inside it may affect its width.
Instead of `isFixed()` checks done in 256901@main, this patch adds missing
check of `width` being PercentOrCalculated.
