Objects inside Vertical Scrolling Frame cannot "fill container"

I am having a problem with scrolling frames.

As you know, if you want make a scrollable area, you need to use a frame and make it scrollable. Now, if you want to make that scrollable frame width responsive (stretchable), you have to Auto-Layout it. But once you do that the frame loses the ability to be scrollable, since it is not a frame anymore.

Any way to solve this or any work around.
