Dragging an object inside the component sometimes leaves the drag source indicator active after drag

1) Create project

2) Add component

3) Open component

4) Add cube

5) Add sphere

6) Drag sphere above the cube so that it is directly under the root component

--> The yellowish drag source indicator color is not cleared from the sphere row.

Dragging anywhere else besides as the first child of the component or as the next sibling from a component seems to update the color properly.
