For prototype, how to disable the "springy" behavior at the top/bottom when dragging up/down?

I would like to know when dragging up/down the overflow content, is there a way to make the top/bottom stop at the edge so my (Red) image content doesn’t get cut off and reveal the (Blue) background with the springy “behavior.” Though would be great too if the top and bottom can be set differently with this effect.

Here is a quick sample in prototype for your reference.

Interestingly, I created a Pixel frame to try out the look and the “springy” behavior is gone! Would it be a default iOS effect that gets somehow implemented in the prototype viewer?
