Make scrollable frames scrollable in design mode

I’m constantly finding myself inconvenienced by the inability to view content outside the scrollable frame in design mode. The only options seem to be either changing the size of the frame or toggling outlines to view the matrix code.

Neither of these solutions are really that great, what would be great however is if there was a way to scroll inside the scrollable frames in design mode.

Perhaps modifier+scroll, or simply when using the scroll while mousing over a scrollable frame.

Thanks!
