Back Tick (tilde) Key (`, ~) Graph Editor Function Curve Resize

Quality of life request.

The Graph Editor resizes function curves if I press the back tick (tilde) key and ENLARGE the viewing area.  Problem is, it DOESN’T restore the function curve to fit back down within the window when I press back tick again and make the Graph Editor smaller. The timeline and curve just get cropped. Please make it so it resizes the timeline and function curve when the window is made smaller again.
