Bug 1732044 [wpt PR 30877] - Add clearance correctly past fragmented floats., a=testonly 

Automatic update from web-platform-tests
Add clearance correctly past fragmented floats.

It used to be possible to squeeze in a zero-height child (in-flow or
floated) at the bottom of a fragmentainer with fragmented floats, even
if the child should have clearance applied.

So, just adding an exclusion that goes all the way to the bottom of the
fragmentainer won't do. That part ensures that containers are stretched
correctly, but we actually need some additional logic to make sure that
we don't attempt to insert content that should be cleared past the
current fragmentainer.
