I came across the tests for custom built-in elements in WPT:
https://wpt.fyi/results/custom-elements/builtin-coverage.html?run_id=478440003&run_id=484130003&run_id=461580002

This bug is about the custom elements API overall, is there a bug about built-in elements specifically?

That would be https://bugs.webkit.org/show_bug.cgi?id=182671 (with the resolution of WONTFIX).

Thanks Ryosuke! I've linked to that bug in https://github.com/web-platform-tests/wpt-metadata/pull/145. It isn't displayed inline on wpt.fyi yet, but would in the future make it clear that these failures are associated with a closed bug and not a new/unknown failure.
