Might want to add a comment on PseudoClassMatches here, mentioning it is an obsolete synonym for PseudoClassIs.

You should not change these tests directly. Changes need to get upstream to WPT from http/wpt/

[Antti Koivisto]

Meanwhile you can just land modified versions outside imported/w3c/web-platform-tests and skips the WPT versions.

[Antti Koivisto]

...or land them as failures.

They've already been changed in upstream <https://github.com/web-platform-tests/wpt/pull/14071>.

Then wait for that to land, re-import (marking failing), then land this patch?
