Fixed another issue where the group was wrongly clipped

For groups which were not clipped rounded or in other ways,
the children would briefly appear when clicking on the group,
leading to a visible flash. We're not applying the clipping
to groups which have launching children.

Test: add group in second slot, observe launch animations
