Short description of error
When you move an object to a collection that is inside another collection and you try to use the arrow keys its direction up / down are inverted
Tested on Windows and Mac
Exact steps for others to reproduce the error
1.- Open the default Blender file
2.- Create a new collection (let's call it "TestCol") within the existing one
3.- Select the cube and press M to see the context menu
4.- In this first menu the arrows up / down work well, but now when you expand the inside of the Collection you will see 3 options: Collection / TestCol / + New Collection.
5.- If within that menu you try to navigate with the up / down arrows, direction will be reversed.
