macOS 14.4 Regression: HTML elements in a WebView (Legacy) do not repaint
when their width/height change
https://bugs.webkit.org/show_bug.cgi?id=270898
rdar://124564409
Reviewed by Matt Woodrow.
After 271261@main we don't update compositing layers on every layout, but when
WebKitLegacy forces
layout, we need to update them. This fixes an issue resizing solid-color-only
layers; for other
layers, the triggered repaint avoids the bug.
I tried to fix DumpRenderTree to respect `testRunner.dontForceRepaint()` so I
could write a test,
but even with this, the runloop observer fires in DRT and updates layers, so
the test didn't work.
