Lightroom Classic: Mouse cursor disappears when creating collection set within collection set

Steps to Reproduce:

Create collection set
Right-click on that and select "Create Collection Set" again
Fill out the name and press Enter key (don't click on Enter with mouse)
Mouse cursor vanishes until you move the mouse outside of the collection list

Minor annoyance if you're building a big collection tree, probably unnoticed in most cases.
