Shows "wrong", horizontally scrolled, empty area where no visuals are placed.

When the individual layers (content, feedback, handles) have different sizes, the scrollable area is sometimes too big, allowing the user to scroll to empty space where no visuals are placed.

To reproduce:
1. Start the GEF4 MVC example.
2. Zoom-in (using Ctrl+MouseWheel). Make sure the zoomed-in visuals fill the whole view part.
3. Select any visual.

The issue was caused by the Group around the StackPane which layouts the layers on top of each other. When auto-sizing is disabled for that Group, there is no empty space to scroll to. The changes are pushed to the master branch, resolving as fixed.
