Pressing backspace when passing None as Search Key prints the word backspace as regex.

Pretty much the title. If you have passed None as search_key, if you are currently searching nothing and backspace is pressed, the search text becomes the literal word "backspace". I found this issue with other keys / combinations as well, like pressing º or ç (with the Spanish keyboard layout) makes the search text become the word italics.

Thanks for your bug report! I already have an idea why this happens. 👍

I think it is related to this issue, so I'm posting it here: pressing the Left Arrow crashes the menu.

Is there any easy fix for this, or can you point to the erroneous code? I could attempt a PR if you have already identified the bug.

EDIT:
Oh, it is a simple fix:

                    self._search_key is None and next_key == DEFAULT_SEARCH_KEY
                ):
                    self._search.search_text = ""
-               elif self._search_key is None:
+               elif self._search_key is None and next_key not in ("backspace",):
                    self._search.search_text = next_key
            else:
                assert self._search.search_text is not None
