Bug 2004086 [wpt PR 56490] - [gap-decorations] Disallow painting decorations behind spanners (multicol), a=testonly

Automatic update from web-platform-tests
[gap-decorations] Disallow painting decorations behind spanners (multicol)

This CL disallows painting gap decorations behind spanners in multicol
under any circumstance. Currently, column rules don't allow this
behavior so for now we will not allow it either, although this might
change in the future. Before this CL we would allow it with `rule-break:
none` but after some discussion we decided it would be better to perhaps
not allow it then.
