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. 1794469 1 webkit-bug-importer 2021-09-17 09:34:14 -0700 <rdar://problem/83244357> 1898851 2 cdumez 2022-09-15 16:32:18 -0700 Pull request: https://github.com/WebKit/WebKit/pull/4407 1899381 3 ews-feeder 2022-09-18 16:05:11 -0700 Committed 254619@main (cf4ebbe5d88a): <https://commits.webkit.org/254619@main> Reviewed commits have been landed.
