Motivation
See T195721: As a user who's editing a text box, I can click on a back arrow to reset the box’s content to what it was when the edit conflict occurred. This back arrow prompts a confirmation, which I see each time I click on the back button.
Acceptance Criteria
- Have a check box saying "Don't ask again" in the confirmation dialogue.
- If the box is checked and the user clicks on "cancel" or "discard", they won't see the confirmation in the future.
