Scrollbox breaks when put inside of another widget

Scrollbox breaks when put inside of another widget

Developer Notes

Works fine. You've likely placed the scroll view into the vertical box and set the slot's Size Rule to "auto" (the default). Auto means, take as much space as you need. If that's the case the scroll bar can never appear because the control will always size to be the size needed to display the content.
Change it to fill and it should work.
