Product Configuration Interface Issue

I am working on a product that is 400 x 200 pixels. I made the canvas 450 x 250 pixels.

The issue is that the element modification tabs get cutoff at the bottom (see image) and the scrollbar only goes to the bottom of the current tab. The only workaround is to increase the height to at least 400 pixels. Can you place full length scrollbars on the wish list?
