Notify user about pending changes in sidebar if he tries to exit #5305

@anaswaratrajan depending on your motivation this could also be a great issue to work on :) (if still reproducable, that is)

Okay, I'll look into this too :D Thanks!

@LukasHirt @pascalwengerter I tried to reproduce this issue. By sidebar, did you you mean the Actions panel that pops up for file actions and sharing? The issue I found here is being able to leave the window in the middle of a copy, move, rename, delete and sharing actions.

Can I try adding an event listener like in #4840 in file ActionsAccordion.vue? :D

@anaswaratrajan let me think this through and get back to you, not sure how much "user interruption" we want in the app :) but could still be a great opportunity to re-use your learnings from #4840 here!
