Reproduce on an iPad using the two screen.orientation.lock("portrait") and lock("landscape") calls described in the issue, then trace the plugin's iOS orientation-lock handling. Done means switching to landscape allows the user-controlled landscape-primary or landscape-secondary orientation instead of always selecting landscape-secondary.
