TypeError undefined is not an object (evaluating 'this.delegate.connect')

[FriedSock]

Hello, we are seeing this error in our bug tracking software. I have not managed to reproduce it, but it is happening fairly frequently, all on Safari/Mobile Chrome iOS (all webkit).

The turbo version is 8.0.5

I can't understand how it is possible as connectedCallback is being called on a FrameElement and the delegate is undefined, suggesting connectedCallback is being called before constructor. Does anyone have any ideas?
