Duplicated Animator does not unlink from the imported .aseprite, and it restores Animation Clips to the original state when saving

How to reproduce:
1. Open the “RPG Game.zip“ project
2. Open the “SampleScene“
3. Open and dock the Animation window somewhere on the Editor
4. Select “Torch_Red“ and in the Animation window, press on “Create New Clip“ to create a new Animation Clip
5. Duplicate the referenced Animator outside of the .aseprite object
6. Save the project
7. Open the Animator window
8. Delete any one of the states
9. Press CTRL+S to save
10. Observe the Animator window

Expected result: Animator does not restore the deleted Animator states
Actual result: Animator restores the deleted Animator states

Notes:

• The first 6 steps are part of the [Internal link] bug reproduction. The reproduction must be completed before reproducing this bug
• Only the Animators where the steps 1-6 were completed on will reproduce the bug
• If the Animator states disappear after step 6, select another Animator or a GameObject that has a different Animator and then select the “Torch_Red“ GameObject again
