1438047 - [wpt-sync] PR 9503 - [LayoutNG] Allow zero-width layout opportunities.

Status: RESOLVED FIXED

(Core :: CSS Parsing and Computation, enhancement, P3)

Description

[Web Platform Test Sync Bot [:wpt-sync] (Matrix: #interop:mozilla.org)]

Zero-width floats or in-flow block-level objects that establish a new formatting
context may fit beside preceding floats even if there's zero inline space left.

With this change, a couple of tests start passing, but coverage seems a
bit low, so I added a few new ones.

Had to rebaseline fast/text/word-break.html because a zero-width line
may now fit beside a float that takes up all available inline
space. There was a <br clear=all> in the test that used to insert the
line below such a float. We're now compatible with the others (and our
old selves).
