Selecting take by dragging with comp tool - unsynced folder

I found a bug or at least an unwanted behavior. Steps to reproduce:

  1. Create two tracks and put these in a folder track.
  2. Enable group editing for this folder track.
  3. Record two takes on both of these.
  4. Expand the lanes on one of these.
  5. Select the comping tool and drag across the lanes to slice and select at the same time.

Both tracks are sliced identically and the same take is selected on both tracks.

Only the one of the tracks is sliced that group editing goes out of sync.
