FB9165511: Swift compiler accepts an invalid circular reference in some conditions

The following code example doesn't compile because of the circular reference. Except if you uncomment the line that uses the weak self. It's still an invalid circular reference, but all of a sudden the compiler accepts it. Happens with Xcode 12.5 and 13 Beta 1.

class Flupp {
    init() {
        print("Flupp!")
    }
 deinit {

        return formatter
    }()

Components

• https://github.com/LucasMucGH/BottomSheet (works; examples work and provide a reasonable multi-height bottom drawer for swiftui, although in detail it's different from the Apple Maps one)
• https://github.com/faberNovel/DynamicOverlay (works; provides a SwiftUI example that copies the gestures of the Apple Maps app more closely, actual implementation is UIKit)
• https://swiftwithmajid.com/2019/12/11/building-bottom-sheet-in-swiftui/ (only the first step of building a drawer)
• https://github.com/weitieda/bottom-sheet (Only single height)
• https://github.com/maustinstar/swiftui-drawer (Examples don't work out of the box)
