Research direction
No source file or test is named. Reproduce the issue in OBS Studio 27.0.1 using the listed scene and group steps, then trace how grouped Media Sources are counted by the Audio Mixer when scenes change. Done means a newly created Scene3 does not show the Media Source in the Audio Mixer unless it should be present.
