Short description of error
If you have an object in a collection, and that object has children; dragging the object
from one collection to another, in the Outliner, will result in the object being moved without its children.
The children will remain in the initial collection.
Exact steps for others to reproduce the error
- Duplicate the default cube
- Parent one to the other
- Create a new Collection in the Scene Collection
- In the Outliner, LMB click-and-hold the parent cube
- While holding, drag to the newly created Collection
