Dragging a Prefab into a Prefab causes odd behavior

[Retroeer]

Describe the bug

If you drag a Prefab into another prefab, some issues arise
Such as the dragged in prefab ignoring any undo's within the main prefab, however if you delete it that gets undone aswell as any prefabs you dragged into it in the past all at the same time
If you drag the prefab into itself and attempt to delete it you get a warning
TreeNode Error: HasChild '[GameObject:GameObject](arg:0)' but not in built children

To Reproduce

1. Create a Prefab
2. Drag the Prefab into itself

Expected behavior

Prefabs inside of prefabs should work as smoothly as they would in a normal scene.
