Bug 1992293 [wpt PR 55189] - Stop assuming scrollbar track is always opaque in cross-axis-scrollbar.html, a=testonly

Automatic update from web-platform-tests
Stop assuming scrollbar track is always opaque in cross-axis-scrollbar.html (#55189)

Starting macOS Tahoe, the scrollbar track is no longer fully opaque, so it starts revealing a red background behind it.
