unicorn/no-invalid-remove-event-listener Correctness
What it does
It warns when you use a non-function value as the second argument of removeEventListener.
Why is this bad?
The removeEventListener function must be called with a reference to the same function that was passed to addEventListener. Calling removeEventListener with an inline function or the result of an inline .bind() call is indicative of an error, and won't actually remove the listener.
