Bug 1766858 [wpt PR 33846] - Pay attention to floats/OOFs changing to "regular" blocks., a=testonly

Automatic update from web-platform-tests
Pay attention to floats/OOFs changing to "regular" blocks.

(and also if they become column spanners)

Don't leave the IsInLayoutNGInlineFormattingContext bit as true, since
they no longer participate in an inline formatting context when no
longer floated or OOF.

Not sure if this is only a problem for column spanners.
