Checkbox instructions disappears on space selection
Pressing i or a works as expected. But selecting item with space, removes instructions.

Hey! This is done on purposes to reduce weight on the screen once we assume a user understands how to operate the prompt.
Does it cause a problem? Would you prefer this to be configurable?
Oh I see. Well it was a little bit unexpected since instructions present 3 options and 2 of them doesn't clear up instructions while only 1 of them cleared it. I'd prefer it to be stay consistent tbh. My vote goes to non-clearing path by default. Configuration option doesn't sound bad.
Let's combine this request with #963
PR #1381 is up with this feature. I'll leave open a few days for review and feedback. Feel free to chip in!
