For one of my scripts, I'm using gum filter on a small list and would prefer to exit the program without selecting anything using a single escape rather than having to hit it twice: first to blur the textinput and again to exit. Note that exiting with ctrl+c isn't a substitute as this results in exit code 130 as opposed to exit code 1, which you get for exiting via escape.

Context: the "unfocusing" functionality was initially added in #776.
