Noticed that onInputChange is being called multiple times with different values when using the Esc key:

This seems to be because of useComboBox's Esc key handling which calls state.revert. Even if we clear the selected key here, that state update doesn't happen yet for state.revert which will cause the second onInputChange call. Ideally we'd drop the Esc key handling from useComboBox but keep the rest of it.

good catch, we should get a test for this as well
