When creating a new Rack with custom height you can't type 32 into the rack's U count.

[cyberfox]

Describe the bug

When setting the custom height, you can't type 32 in, because the '3' is treated as a shortcut for the 24U prior selection.

Expected behaviour

When selecting Custom you should turn off the keyboard shortcuts for the other buttons.

Steps to reproduce

1. Open Rackula
2. Name it
3. Select Custom for the rack's U count
4. Try and type '32'; typing any number 1-4 closes the custom prompt.

Hey @cyberfox thanks for reporting this. Seems I mangled something when introducing keyboard shortcuts for accessibility.
