performKeyEquivalent is [documented](https://developer.apple.com/library/archive/documentation/Cocoa/Conceptual/EventOverview/EventArchitecture/EventArchitecture.html#//apple_ref/doc/uid/10000060i-CH3-SW10) to be called even if a view isn't first responder (this is for example how "Enter" binds to the default button on a dialog, for example -- the default button doesn't need to be focused to respond to Enter), but since we override performKeyEquivalent to properly support certain keyboard shortcuts (like noted in #1867), the previous assumption on the actual use of performKeyEquivalent no longer holds -- it's *only* for keystrokes sent in focused state, so add that check.

Summary:
Consider a hypothetical situation where a multiline TextInput handles (by dequeueing from the event queue) Cmd+Enter. If the focus is on another control that also handles Cmd+Enter, then hitting Cmd+Enter will not reach this other control -- in fact it will perform the action for the former TextInput, as if it were focused!
performKeyEquivalent is documented to be called even if a view isn't first responder (this is for example how "Enter" binds to the default button on a dialog -- the default button doesn't need to be focused to respond to Enter), but since we override performKeyEquivalent to properly support certain keyboard shortcuts (like noted in #1867), the previous assumption on the actual use of performKeyEquivalent no longer holds -- it's only intended for keystrokes sent in focused state, so add that check.

Manually tested affected scenario for correct behavior.
