When I drag over multiple layers for their appearance, Designer shows the drag & drop layer cursor. This can be confusing, because it may seem like you are in fact dragging and dropping a layer in the studio, even though it doesn't move layers around (fortunately!). This occurs in all of the Affinity V2 apps for Windows 10 (21H2).

Expected behaviour
I would expect not to see the cursor change when I drag over a layer in between the area designated for FX, Locks and Visibility.
