MudSelect OnKeyDown event is not invoked on alphanumeric characters input while selection combo is open

What happened?

MudSelect OnKeyDown event is not invoked on alphanumeric characters input while selection combo is open. I am trying to implement multi-character (subsequent character input) search for items to be selected on multiple subsequent key presses, (I believe it is not supported at the moment, which is another issue/feature request for me) probably using some kind of event to intercept the input, listen for another key press and maybe use a timer to differentiate between subsequent multicharacter search and another new search. I tried to use OnKeyDown but it is NOT invoked for alphanumeric characters, while selection combo box is open. It works while options combo is closed.

Also maybe another issue is, that the automatic selection of item starting with the letter pressed works only, while selection combo is open. When it is closed, but MudSelect still has focus and user presses alphanumeric characters, this limited first character only search feature also does not work. But it is another issue I guess.

Expected behavior

OnKeyDown is invoked even while MudSelect selection combo is open.

Bonus features:

• search function works while MudSelect has focus, but selection combo is closed.
• MudSelect provides a way to customize search/select algorythm
