Description Dirk Fauth CLA 2023-02-22 07:44:32 EST 
If you try to reorder a collapsed group in a performance column/row grouping to the edge of the group, the group gets modified which leads to strange rendering issues. The reason is that the resulting reorder event implies that only a single columns was reordered, which triggers the action to modify the group (remove the first or last column from the group).

If a collapsed group is reordered to either the left or right edge of the same group, actually no reordering needs to be performed. This avoids the side effects in those special cases.
