Description Ahmad Saleem 2023-09-02 18:47:17 PDT

Hi Team,

In attached test case, we regressed following in STP177 compared to Safari 16.6:

> patternMismatchFor("unicode-invalid-01") should be false. Was true
> patternMismatchFor("wrong-email-address") should be true. Was false.

Just wanted to raise so we can fix it.

Thanks!

Chromium and Gecko also fail the wrong-email-address one (as well as disabled). But they don't fail unicode-invalid-01 so that one seems like a problem.

Retitling, since one of the "failures" matches all browsers.
