Bug 1698664 [wpt PR 28090] - Fix painting of composited overflow controls with visibility:hidden, a=testonly

Automatic update from web-platform-tests
Fix painting of composited overflow controls with visibility:hidden

We can have a composited scroller with visibility:hidden if it has
visibility:visible descendants. We should skip painting of overflow
controls in the case. Ideally we should not create composited
overflow control layers, but I would not touch the
pre-CompositeAfterPaint code for the rare case.
