Children of MathML containers always establish a new FC.
Just like flex and grid items, children of MathML containers establish a
new formatting context. When falling back to legacy layout at a
descendant, stop legacy fallback propagation at such ancestors (since
they cannot be laid out by the legacy engine - no implementation there).Add a DCHECK to catch such problems earlier (rather than in layout).
This also fixes a similar issue for css-layout-api, unless we make an
extra effort not to fix it. :) So added a test that used to DCHECK-fail
in the exact same way.Bug: 1178979
