Created attachment 342481 [details] Scroll animation When you are inside fixed element, and scroll position is at 0, scrolling to top will actually trigger scroll of the body, and while that scroll animation has not finished you can't interact with fixed element. This can be confusing when fixed element takes full body size, so the whole screen is locked and you dont know why. See the attached animation for better idea whats going on.

This is because UIKit prevents scrolling of the page when rubber-banding is in progress. It's not a great user experience.

I don't think there is any action planned for this use case at present.
