Why is deinit not called here?

If a StateObject's lifetime is that of the containing view, popping from the stack should deallocate it. But it doesn't.

Weirdly removing the List's selection binding results in a dealloc as expected.

Is this a memory leak with List or am I missing something? (iOS 17/latest Xcode)
