Move item contents and edges with grouped items

[AndiS]

The behaviors
- "Move item contents ignoring snap, ripple all adjacent items"
- "Move item contents ignoring snap, ripple earlier adjacent items"
- "Move item contents and right edge ignoring snap, ripple later items"

in context[s] "Media item [bottom half]" don't work as expected with grouped items (even with all the items in the group selected). The contents move as they should in all items, but the ripple part only works with the item you actually touch with the mouse.
Tested in v6.27 under Linux and Windows, but I remember getting the same behavior in earlier Versions as well.
