This has never happened before on SE, not even earlier today in a different stack.

I wrote a question and clicked "post." Immediate pop-up "Are you sure you want to leave this page?" I assumed (incorrectly) that something had gone wrong. So I said No and tried again. oops! duplicate post.

Then I saw a typo and tried to fix it. When I clicked Save, same pop-up, with a busy spinner on the Save button. Clicked yes (leave), and saw that the edits had actually been saved.

  • $\begingroup$ It did not happen when I posted this question. However, when I edited the question it did happen, AND an earlier version of this comment disappeared. $\endgroup$

    $\begingroup$ @WGroleau I just got basically the same behavior as you, using Microsoft Edge on a Windows 10 machine. When I clicked "Cancel", my answer showed as being blank! However, refreshing showed that the edits were saved. Like you, this has never happened before, and I haven't made any recent machine changes (e.g., any updates). Thus, I suspect SE has changed something recently to cause this to happen. I'm not sure if this is just on the Math site, but you may wish to check if it's also on other sites and, if so, write a bug report on the general Meta SE site. $\endgroup$ Commented Jan 12, 2022 at 0:43

    $\begingroup$ @WGroleau FYI, this is already reported on Meta at Editing a post leads to a weird behavior. A comment there indicates it's also been reported on meta StackOverflow at Getting "You have started editing this post. Abandon this edit?" when saving an edit. $\endgroup$ Commented Jan 12, 2022 at 0:58

    $\begingroup$ Ditto for me, WGroleau, and @JohnOmielan! Using Firefox. $\endgroup$

    $\begingroup$ I can confirm it occurs on Safari when you edit an answer too. $\endgroup$

  • $\begingroup$ Same error happens to me, too (using both latest Firefox and Chrome on Win10) $\endgroup$
