>>>> isearch uses overriding-terminal-local-map, so the proper test case is:

>>> The docstring of 'overriding-terminal-local-map' says:
>>>
>>>   Per-terminal keymap that takes precedence over all other keymaps.

>> 1. use special-event-map in isearch.el the same way as isearch.el uses

>>
>> 2. use the hook ‘delete-frame-functions’ to explicitly exit isearch.
