This seems to be identical to isInput(), which then I wonder if there's a need for separating out these checks, especially now given that getInput abstracts out which ref is in use (i.e. change isInput to use getInput instead of inputRef).

I was thinking it may be better to have it separate if there's ever a future case where textarea vs input needs to be specifically targeted?
