I propose a simple change of blocking of the CTRL + Z keyboard shortcut, when user is focused in the Filter Box

The purpose o this is also simple: when I write some filtering expression, I often accidentally delete some portion of it and then without thinking press quickly the CTRL + Z; which in turn instead if bringing me the deleted potion of expression, reverses my last change done on files. And sometimes I do not even remember what was the change. And I just can't help this impulse no matter how many times I perform this error

That current behavior of Mp3tag is just so annoying and counterproductive
