Take Lanes: Undoing clip overlapping leaves empty lanes (Confirmed by CW)

Jlien X
There are a few scenarios in which Sonar leaves an empty take lane or lanes without your knowledge (if you normally work with lanes collapsed). The below test shows one of them.
 
1. Create a new project.
2. Drag a long, audio or MIDI file (more than 7 bar-long in this test) from the Browser into the Track view's Clips pane, at the start of bar 1. (Let's use an audio file called "DBD_175_A_MUSIC_LP5" in Audio Library->Loops->Loopmasters->BREAKS DRUM N BASS->DANNY BYRD)
3. Hold CTRL and drag the clip to the start of the next bar (to make the clips overlapped). Repeat this 4 times.
4. Click the Expand/Collapse Take Lanes button in the track header to expand the lanes. Your Track view should now look like this:

 
5. Hit CTRL+Z (undo) until you see only the original clip.
 
[Expected Result]
Lanes 2-6 (T2-T6) are automatically deleted by the undo's.
 
[Actual Result]
Lanes 2-6 are still there, wasting precious screen space, like this:

I wish Take Lanes had an auto-empty-lane-removal feature.

Of course, but doing that in many tracks is a bit of a hassle. I think I want a shortcut key for the Remove Empty Take Lanes command...
