[Fixed in 2015] Status of PRV's note button not remembered with project/screenset

It's this button (officially called Show/Hide Track button) -->
 
[Steps]
1. Create a new project.
2. Insert two MIDI tracks and drag a MIDI file from the Browser into each track.
3. Select the two tracks and hit Alt+3 to open the Piano Roll view.
4. Adjust the zoom level so that you can see note events of both clips in the PRV, like this:
5. Click the note symbol button of the first track to hide the note events of the track (so that you can only see the note events of the second track in the PRV).
6. Save, close and reopen the project (see the Expected and Actual results below at this point).
7. Repeat step #5.
8. Right-click on the PRV's tab and enable "Lock Contents" if you like (although this isn't supposed to remember the status of buttons).
9. In the Control Bar's Screenset module, lock the current screenset.
10. Switch to another screenset and then switch back.
 
[Expected Result]
Only the note events of the second track are visible in the PRV.
 
[Actual Result]
Note events of the first track are also visible in the view.
