Mouse cursor shape is not updated in piano roll (0.3.0 AppImage)

[swesterfeld]

Typically, if you use the piano roll, the mouse cursor shape changes as you hover over the notes. For instance, if you hover over the end of a note, a different cursor is shown, to indicate that clicking would change the length of the note.

In the 0.3.0 AppImage, the mouse cursor shape doesn't change at all while using the piano roll.
