If you want to use the Esc key to perform a certain action in-game, you can’t do that without manually editing options.txt. Clicking on a keybind option then pressing Esc will simply unbind the control from whatever key, rather than assigning it to the escape key.
To fix: make pressing Esc correctly assign that control to that key. A new user interface button could also be added to unbind each control, if this functionality is desired.

I would strongly disagree on the duplicate resolution - both tickets deal with Esc being strange, but these are clearly two very different effects that simply happen to share a button.
A comment on MC-308123 states that Esc simply cancels the rebinding process. In that scenario, instead of unbinding the key, should it not simply stop the game from listening to keys and revert the binding to whatever it was before you clicked?
