Comment 10 for bug 138500

I don't understand what it would mean to have a "No, undo" button alongside a "Yes, continue" button. Either the reassignment has happened, in which case "continue" would be a no-op, or it hasn't happened, in which case "undo" would be incorrect.

All that would be necessary for an "Undo" button would be a <form> with a hidden assignee field representing the previous assignee, so clicking the button would reassign back to him/her.
