Since the last update the marker line in the piano roll view stays in the location where it has been upon exiting the piano roll section with the mouse, even after moving out the cursor to entirely different UI elements.
It's only fading out if I move the cursor out of the piano roll section to the right or through the bottom. If I do it to the through the top (which is the most likely scenario), then the marker line will be drawn indefinitely or until I move the mouse into the piano roll section again.
