Bug 2D Skin with AlwaysUpdate Unchecked will not Deform Anymore after culled and comes back into view

Hi Im tying to make some persistent 2d characters play death animation persistently.
But it seems there is something changed in 2021.3.
As the 2D Skin Unchecked AlwaysUpdate,will stop Deform after being culled out of the View.
But it was supposed to continue Deform when it comes back into the view of the Camera as it was in Unity2021.2 .
Is this an optimization that will never be fixed in the future?
Or is there any code could make the skin execute Deforming again when it comes back into the view?
Thank you .

 

OK!
