Filing this for a colleague who ran into it. In Safari, if you load an iframe while typing in a text input, undo stops working in the text input.

Here's a reproduction:

It's been mentioned on stackoverflow before:

Which has another reproduction:

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).

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!
