On my Safari, I am having trouble even focusing the button. Even clicking the button does not seem to fire its focus event. On Chrome, I can click the button and I get the focus event. The order of the events is what I would expect in Chrome. 1758149 2 webkit-bug-importer 2021-05-07 20:16:14 -0700 <rdar://problem/77685855> 1902205 3 ahmad.saleem792 2022-09-29 15:28:32 -0700 *** Safari 16 *** "visibility changed", "hidden" "visibility changed", "visible" *** Chrome Canary 108 *** visibility changed hidden visibility changed visible *** Firefox Nightly 107 *** visibility changed hidden show:57:33 visibility changed visible show:57:33 ______ All browsers are matching with each other, do we need to do anything more? Thanks! 1902221 4 rsnow 2022-09-29 16:38:50 -0700 Doesn't look like they all behave the same. Note the order of blur/focus VS visibility. Everything is still in the same order as it was when I first filed the issue. *** Safari 16 *** [Log] blurred (show, line 57) [Log] visibility changed – "hidden" (show, line 57) [Log] focused (show, line 57) [Log] visibility changed – "visible" (show, line 57) *** Chrome 105 *** blurred visibility changed hidden visibility changed visible focused *** Firefox 105 *** blurred show:57:33 visibility changed hidden show:57:33 visibility changed visible show:57:33 focused show:57:33 See how Safari still fires visibility change after focused instead of before?
