splitVC.primaryBackgroundStyle = .sidebar leads to busted table view animation

I am building a Catalyst app with "Optimize Interface for Mac".

If a use mainSplitVC.primaryBackgroundStyle = .sidebar and add animations for table view, it leads to bad animation.

You can see the video here: imgur.com/a/1Kn4RVA

(Don't know why I cannot attach and video or image here)

This should be a bug for Catalyst. Also filed a bug report:
