Shell commands triggered from action tags used to block polybar until they finished. Since we are not actually interested in the output of the commands, it makes sense to run them completely detached from polybar and have polybar not block when executing these commands. Now the spawned child processes no longer get killed when polybar exits. This is fine because polybar is not responsible for these processes since they were explicitly started by the user through click commands. Ref: #770 Ref: #1680
