I think it may be subtler than that, but more easily fixed:

When the contents of a group are resized, by default the group enclosing 
them is resized to fit.

So if you set the lockLoc of the group (and here I tend to set that for 
objects in groups as well, just to avoid my accidentally moving them 
while working) you should find it resizes more gracefully.

Also, unless you need the margin you may find it helpful to set the 
group's margin to 0.  If you leave it at the default of 4 and move its 
internal contents to any edge of the group, when the group's lockLoc is 
true the internal objects will render clipped, and when the lockLoc is 
false the group will expand by 4px to accommodate the control.
