Subject: [PATCH] Bug 1610245 [wpt PR 21257] - Add tests for baseline,
 stretchiness and spacing in unknown elements., a=testonly

Automatic update from web-platform-tests
Add tests for baseline, stretchiness and spacing in unknown elements. (#21257)

See https://github.com/mathml-refresh/mathml/issues/139

This also fixes wrong mpaddednotation attribute and repeats spacing tests
for other mrow-like elements.
