Nested containers: is it possible to reduce the parent container size when a child container collapses?

[cswrd]

Hi,

given

when I expand the inner box I'll get (which is ok):

but when I collapse the inner box again I'll get:

The outer box will keep its size. Is it possible that it'll collapse automatically, too such that it looks like in the beginning again?

Due to this behaviour it's quite cumbersome for me to draw bigger diagrams with many nested and sibling containers. When I need to edit an inner box, I have to expand many boxes messing up the layout, that I have to manually resize over and over again.
