Remove Max limit for sequence widget vertical size

Is there any reason why the widget displaying the graphical features cartoons cannot be resized beyond a certain limit? See attached image: the part highlighted cannot be resized at will, and this is a problem when the DNA has a lot of features.

It would be nicer if the user could resize that part as much as they want. For instance, my sequence has a lot of restriction sites and it's annoying not to be able to see them all at once on the screen.
