Small bug in the new layout option for empty staves

Small bug in the new layout option for empty staves: When you select the “Layout Options” option menu, the list of instruments/voices sometimes appears completely, sometimes collapsed (but still scrollable). You only need to open and close the layout options menu. A small bug?

Thanks for reporting this. I’ll keep an eye out for it happening myself.
