Short description of error
If you switch the Outliner to Scenes mode and drag a collection to another collection, "Link inside Collection" is displayed but in reality, the collection is moved and you have to press Ctrl to link it.
Exact steps for others to reproduce the error
Add a new scene. In the Outliner, switch to Scenes mode and drag a collection from the original scene to the new scene. Notice that the tooltip is "Link inside Collection" but if you don't press Ctrl, the collection is moved, not linked.
