How to prevent which-key from sending presses that aren't mapped to the editor and instead just close?

[yanshay]

Hi,

Is there a way to configure which-key so when an unmapped sequence is pressed it will just close and do nothing with the pressed keys accumulated until it closes?

Example to explain the issue:

I don't have <leader>fd mapped to anything. When I press that though, which-key opens, switches to the 'f' menu and when I press 'd' (that isn't mapped after 'f') it closes and pas 'fd' to the editor which acts as if 'fd' was pressed.

If I press <leader> followed by key sequence that doesn't have any meaning and doesn't normally do anything in the editor (e.g. 'gt'), which-key close and cursor moves to the next character.

Some other sequences cause other effects.

So is there a way to achieve what I'm looking for? Just ignore any presses that don't match key mappings which-key is aware of?
