AFAIK that's the case. That was added to allow groups to be
self-contained when used to implement custom controls.
Imagine what a mess the DataGrid would be if you used in a stack in
which your resizeStack handler changes the DG's rect.
By allowing a group to be able to handle a resize no matter how that
resize happens, it can take care of its contents automatically.
Another enhancement added during the same period is that groups now have
their own selectGroupedControls property. It defaults to true to allow
the global property of the same name to govern whether you can interact
with the group's contents with the pointer too. But when set to false
the group's contents don't respond to the pointer tool at all, allowing
it to behave more like a native control.
These enhancements, coupled with behaviors to drive them from a single
script, open up all sorts of opportunities for crafting reusable custom
