Bug with vertical scroll and pan score during playback

I set MuseScore to scroll vertically. When I play a score with more than 1 page, there's a bug with the feature "Pan score during playback" when switching pages.

I attach a screencast showing the problem:

1) Playback is started in the middle of the first page.

2) When it switches to page 2, I scroll down the page a little bit with the mouse.

Results: MuseScore now displays the second half of the page 2 while it's the first half that is played, and there's no way to display again the first half.
