VLC stop playback if window with second video stream is closed

If there is more than one video stream in container (example: m2ts from Coraline Blu-ray, first video stream is film itself, second video stream is storyboard) right after opening video file VLC playback first stream in main window and second stream in separate window. If user close window with second video stream then playback stopped. There is workaround-way to close window with second video stream without stopping playback: select Video > Video track > disabled and then Video > Video track > Track 1 (or Track 2). Reproduced with VLC 1.2.0 git.

By the way opening second video stream in separate window is really should be default behaviour for files with more than one video stream? Maybe VLC should just playback first video stream without additional windows?

I need to provide sample?
