Hello! I appreciate your intention to fix this, but perhaps it is OK that disable_by_keypress can never become false for a particular page. It is hard for me to come up with a scenario when re-enabling it would be undesirable, but still, I want to play safe in this case. I also currently don't have enough time to fix it in case something would go wrong.
