Steps to reproduce
Create item (1) with child (1.1) Create an item underneath this parent item (2) (same level as (1)). Attempt to drag (1) underneath (2) using the Drag item under an empty or collapsed item feature.
Hierarchy is as follows:
After performing the action it should look like this:
The “grey bar” doesn’t appear under (2) when you attempt to drag the item under it. Collapsing (1) or trying to place the item underneath a different item (e.g. a sibling other than (2), such as a different one above or below) works fine.
Note that if (2) is the last item at the level it isn’t even possible to drag (1) below it (not just underneath it). However if you add another item (say (3)) that’s a sibling below (2) then you can now drag (1) below (2) however you still cannot drag it underneath it. The screen recording below shows this.
