UIFindInteraction UI is not usable when Stage Manager is enabled

I have a problem with presenting the new find panel in an iPad app when Stage Manager is enabled. This happens both on device as well as in Simulator.

The problem is that UIFindInteraction’s find panel only flicks (appears and disappears in a fraction of second) and thus is not usable for actually searching anything.

Presumably, this is a UIKit bug. Has anyone found a way around it?

I'm attaching a link to a demo project that does nothing special:

1. setting isFindInteractionEnabled = true on a UITextView
2. preseting the find panel via textView.findInteraction?.presentFindNavigator(showingReplace: false)
