Negative Z offset works with numpad but not -_ key

[hackwin]

Description of the bug

Negative Z offset is sometimes entered to get the print to stick better to the bed. In Prusaslicer, a negative value can only be entered using the "-" key on the numpad. The "-_" key to the right of the "0)" key does not work in the field.

Project file & How to reproduce

Printers -> General -> Z offset:
Enter a negative value using the "-_" key and it doesn't work. The "-" key on the numpad does work. Both keys should work and do the same thing.
