Automatic update from web-platform-tests Handle resumed blocks that get sliced by floats correctly. Floats may be pushed from one fragmentainer to the next, and thus get in the way for blocks that started in the former fragmentainer, which means two things: 1. The resumed block may not start at the fragmentainer block-start (this was already working correctly) 2. The resumed block may not be able to fit anything at all in the next fragmentainer (if the float is tall enough). This was failing. We'd end up inserting a break before a node that we had already started, causing a lot of trouble. We'll now allow fragments of resumed blocks even if we're out of space (their block-size will typically be 0, i.e. no visual effect). We cannot just break before them, as that would restart layout from scratch once we get to a fragmentainer that has room (and a lot of other weirdness, e.g. confusing anyone trying to use the break token sequence numbers). As for the crash test included in this CL, we'll actually fit a portion of the nested multicol container below the content edge of the float in the first fragmentainer, and then resume the rest after the tall bottom padding of the float (which gets pushed to the second outer fragmentainer, since it's unbreakable). This is a bit weird, but probably acceptable.
