Subject: [PATCH] Fix scale highlighting during vertical zooming (#6761)

Vertically zooming the piano roll caused highlighted semitones to drift from the actual note positions. This 2-line fix ensures the marked semitones are aligned with the grid lines and notes at all allowed vertical zoom levels.
