📄 Description

For some weird reason we sometimes receive a WM_KEYDOWN
message without vkey or scanCode if a user drags a tab.
The KeyChord constructor has a debug assertion ensuring that all KeyChord
either have a valid vkey/scanCode. This is important, because this prevents
accidential insertion of invalid KeyChords into classes like ActionMap.

PR Checklist

Validation Steps Performed

  • Tab dragging doesn't produce assertion failures anymore ✔️
