Fredrik Söderquist · chromium-wpt-export-bot · commit 91eaa6dca62b · 2025-11-21T10:24:01.000-08:00
Move the test and perform a mechanical rewrite: * Change assertComposition() to test_composition(). * Change 'is' to 'expect' in the expectation objects. * Include required testharness.js and framework. * Add link to spec.
