REGRESSION(282068@main): Flashing scrollbar on Spotify when hovering the
fullscreen button
https://bugs.webkit.org/show_bug.cgi?id=282793
rdar://138918575
Reviewed by Simon Fraser.
The temporary glitch is a pre-existing unstable layout bug that was papered
over using body::-webkit-scrollbar { display: none } as a workaround.
Spotify also uses body { scrollbar-width: none }, and per-spec, any non-default
scrollbar-width value makes ::-webkit-scrollbar styling ineffective, so this
workaround no longer works.
While we investigate the root issue further, make a quirk to make
`scrollbar-width: none` no-op on body for now, to address the customer issue.
