Ugh, I’m not surprised, safari really is the ie6 of the future.<p>From an outsider’s perspective, they really seem to go out of their way to implement specs differently from everybody else, and they don’t bother cross-checking until users file bugs - which is largely too late because fixes are tied to iOS releases most of the time and won’t get released till the next year<p>(I ran into a similar issue a few months back with samesite cookies, which works for all other browsers - even edge - but not safari)
Yes! This is so strange because it works on Chrome and fine with a async call that completes under 1000 ms so long as it doesn't do a AJAX request.
