Clicking "Edit" on a question freezes the tab.

[crackwitz]

Describe the bug
Hit 'Edit' on any question, then the tab freezes from some infinite loop.

To Reproduce
Steps to reproduce the behaviour:

1. Go to any question (pick from questions page)
2. Click on 'Edit' which is right under the question
3. Throbber animation next to the 'Edit' appears, but the entire tab refuses to respond to any input, including mouse hovers and attempts to close the tab in some ways

SOX errors logged in console
I managed to grab part of the log. This here repeats hundreds of times a second:

Expected behaviour
No tab freezing and infinite loop.

Environment

• SOX 2.9.0DEV (as presented here: SOX breaks user search in chat.stackoverflow.com/users #513 (comment) )
• Chrome, latest update or close to it by days
• Tampermonkey 5.4.0

Thanks for the bug report @crackwitz!

This should now be fixed in the latest dev version v2.9.1 - please let me know if it works!

[crackwitz]

v2.9.1 DEV still behaves the same way here. Maybe it's some kind of interference on my end. I have a few more userscripts and browser extensions. When the issue occurs, I see no "third party" logging in the console, only SOX. At least none of the other userscripts are to blame because the issue persists even if I disable all but SOX.

Deselecting the "Pre-defined edit comment options (checkboxes)" restores functionality.

I did see new checkboxes under some editor/input box recently (editing an answer?), after the update to v2.9.

[crackwitz]

The freezing and event looping only happens when clicking "Edit" under a question (and with the checkboxes option active). It always works fine under answers.

@crackwitz sorry for the delay in getting back!

please could you share the full browser console output again when you use v2.9.1 dev?
