Hello and thank you for this bug report! I'm not sure that this dash is a common window. Is it possible to launch these two commands from a terminal, select your Unity Dash (I guess you can open it with a shortkey or you can add a delay by adding 'sleep 5 && ' before these commands) and post here the output messages in your terminal:
