In Safari, if you load an iframe while typing in a text input, undo stops working in the text input. Here's a reproduction: http://jsfiddle.net/4qsfya3a/2/ It's been mentioned on stackoverflow before: http://stackoverflow.com/questions/10810246/iframe-load-clears-browser-undo-stack Which has another reproduction: http://jsfiddle.net/N6t8P/6/ The stackoverflow question implies it's also broken in Chrome. However, I've found this works correctly in latest Chrome and Firefox (didn't try IE). 1126039 1 webkit-bug-importer 2015-09-15 10:52:23 -0700 <rdar://problem/22704530> 1905952 2 ahmad.saleem792 2022-10-16 04:32:19 -0700 I am able to reproduce this bug in Safari 16 and Safari Technology Preview 155 using attached test case and CMD+Z opens previous closed tab (if not in Private Mode). Both Chrome Canary 108 and Firefox Nightly 107 also has differences where Firefox do CMD+Z and remove all text, Chrome go character by character. Just wanted to update latest results. Thanks!
