[Recorder] Start/Stop recording is altering the playmode as well
(Ported from Github)

2. How we can reproduce it using the example you attached
1. Click on play in the scene
2. Now open the recorder and click on start recording
3. Click on stop recording after sometime

Note that the playmode is also stopped. The user expects that the recording alone stops while the user can continue playing.
