Sizing of SectionStack in an expansion component

[fatzopilot]

Hi,

I tried to use a SectionStack in the expansion component of a list grid to make editing a complex record more clear.
So far, I've failed to size the SectionStack to accommodate its dynamic content (actually other expandable grids with variable content).
Either the size (width/height) is fixed (and thus the SectionStack has a fixed size, see fixed_sizing.png), or it is set to "100%" or "*" and the SectionStack just appears as a small stripe without functionality (see attached screenshot, see dynamic_sizing.png).
A modified showcase example to demonstrate the issue is attached (SectionsCustomControlsSample.java).
Is it possible to resize a SectionStack dynamically to fit its content at all?

Thanks

Setting

DetailsStack.setWidth("100%");  
DetailsStack.setHeight("100%");
DetailsStack.setOverflow(Overflow.VISIBLE);

and for all contained canvases

Canvas.setOverflow(Overflow.VISIBLE);

solved my problem.
