In #916 I fixed support for shortcuts that were modifiers only. However, I mistakenly null checked the modifiers array instead of length checking it.
This allows for setting and registering a shortcut that has no key trigger conditions. I'm not exactly sure what is going on with shortcuts like this but they do wacky things and trigger "randomly" when they shouldn't.
