LockLoc and grab

[David Epstein]

A group with lockLoc set to false does not resize itself when an object in it is moved by a “grab” command.  Is this a bug?  Is there a simple workaround?

Recipe using 10.0.0 dp6 on an intel Mac:  

Create a button with this script:  
on mouseDown; grab me; end mouseDown.  
Group the button.  Confirm that the group’s lockLoc property is false.  Then with the browse tool, drag the button past the edge of the group.  The button disappears.
