Automatic update from web-platform-tests *.any.js: explicitly list defaults, part 3 *.any.js's META global no longer supports negation or the default feature making everything a bit easier as a result. See https://github.com/web-platform-tests/rfcs/pull/52, #23117, and #23121. Closes #23111. -- wpt-commits: 96c7f0b57b704c94a7535d58009500ea94c02995 wpt-pr: 23133
