#43 "Select mode" pattern moving in the song view works in a weird manner

[Lassi]

Version: 0.9.6-svn [Mar 16 2012]

When using the "Select mode" in song structure view:

1. Select all patterns in the view with mouse (by painting)
2. Move the patterns vertically (so that entries stay on the line they are)

Expected result:
The enabled patterns are moved in the editor to the new position, same patterns enabled as before the move

Actual result:
The pattern enable status is toggled: the patterns that were enabled before are disabled after the move, and vice versa. (So, moving the patterns acts as a "toggle mask").
