Cannot move a directory to its upper neighbor empty folder by dragging

[aminya]

Summary

I cannot move a directory to its upper folder by dragging when the neighbor is empty. It works to all other folders, but not the upper neighbor. It works if the folder is not empty.

This happens on 1.54.0-nightly1 or 1.51.0

I debugged the code. The issue is that the drag-over class is constantly removed or added when I drag over the upper neighbor. But for all others, the class stays what it should be.

These two methods do this:

tree-view/lib/tree-view.coffee
