Keypad equals key has a completely blank name in Key Binds menu

Likely related to MC-263708 and MC-132076.

The bug

If a control is bound to the keypad equals sign in the Key Binds menu, the name of that key will be rendered completely blank.

A translation key exists for the string:

"key.keyboard.keypad.equal": "Keypad =",

it, however, appears to go completely unused, likely for the same reason as MC-263708.

How to reproduce

1. Bind a control to the keypad equals key
2. Observe

Expected results

The name of the key would be given as "Keypad =".

Actual results

The button renders completely blank.
