Scenario: Locking the KC_LSHIFT, and then using a tap dance key that registers a S(KC_9) will unregister the KC_LSHIFT. The tap dance or any keycode that is registered should not have the side effect of cancelling a locked moditifier. We should be using a similar logic as the TMK codes in tmk_core/comman/action.c:158.
