Yes, this is pretty much what the hardware sends, intentionally, so the
software can figure whenever the event is a autorepeat event or not.

These days most software just ignores repeated events from the hardware
and generates them in software instead, to not depend on the keyboard
hardware capabilities for autorepeat.

UIs are not consistent here.  But, yes, we probably should just allow
down events even if the key is already in down state.
