How to add a combined shadow to expandable table cells?

Question

I have a table view with extensible text cells, each cell has a white appearance with a shadow as a background.

For design, I want to merge the shadow of the cells as an image:

So, I removed the “Clip Pickup” check from the cell.

But I had a problem with the extension of the animation, while the animation looks like this:

The animation problem was fixed when I added "Capture Clips" again, but the shadow was distorted and cropped.

Is there a way to keep the shadow and the right animation?
