When processing shortcuts, set seat->kbd.last_shortcut_sym. This ensures the corresponding release event is ignored in the main mode, if the shortcut triggered a mode exit. For example, pressing Return in search mode would exit search mode, and then immediately reset the search match, if the kitty keyboard protocol mode with release events were enabled.
