Moving the origin to the center of the mesh selection with fixing instances

The script we wrote for quickly moving an object's origin to the selection works well. As long as instances aren't used in the scene. Moving the origin to the selection on an instanced object will cause all instances of the object to move from their original positions to the new ones. This happens because by moving the origin relative to the object's geometry, we're essentially moving the geometry itself relative to its center point, and then moving this center point (origin) to the new position. For instanced objects, the origin remains in the same place, and the geometry's offset doesn't disappear, resulting in a jump.
