Lane Heights Not Preserved

I have a MIDI track with multiple takes. It displays in the project window with one lane per take.

To save vertical the project window, I reduce the heights of these lanes to the minimum. But when I save the project and close Cubase, and then relaunch Cubase and open the project, the heights of the lanes revert to something significantly larger than the heights I set them to before I saved the file.

It would be useful for Cubase 9 to remember height settings for tracks and lanes.
