Morten Stenshorne c05103d326 Bug 2038534 [wpt PR 59779] - Ruby: Only handle overflow if there's content., a=testonly 
Automatic update from web-platform-tests
Ruby: Only handle overflow if there's content.

If there was a float after a RUBY element with just whitespace inside,
the float would be seen as a leading float in PositionLeadingFloats(),
which seems correct. At the same time, however, if `text-indent` was
larger than the container inline-size, such a RUBY would trigger a line
break before the float (which was seen as leading), causing some
confusion.

The crash in `PhysicalContractedBoxRect()` / `FragmentForEdge()` is from
new code, but the assumptions that the new code makes there should be
valid. Fix the underlying issue instead, which is also a ruby
correctness issue. Include one test for that, and one test for the
multicol crash.
