Description Domenic Denicola 2021-09-10 09:33:47 PDT

See the spec change in https://github.com/whatwg/html/pull/7042 and the tests at

- https://github.com/web-platform-tests/wpt/pull/30398
- https://github.com/web-platform-tests/wpt/pull/30418

For data: URLs, Safari seems to allow redirects in iframes, and hang the load forever in top-level windows.

For about: URLs in iframes (didn't test top-level windows), Safari seems to allow redirects to about:blank and about:srcdoc, but give a network error page for about:nonstandard.

In all cases the newly specced behavior is to display a network error page.
