Description Dirk Fauth CLA 2022-11-02 03:57:17 EDT 
In a setup that combines the ColumnGroupHeaderLayer with the GroupByHeaderLayer, the column groups can't be reordered. This can be seen in the _815_SortableGroupByFilterPerformanceColumnGroupAndFreezeExample.

The reason is the ui binding ordering for the drag modes. As the column group header and the groupby header are part of the column header region, the more specific matchers need to be in the registry first. Otherwise the less specific matchers get active first which skips the more specific ones. As the GroupByHeaderConfiguration adds the DragModes via registerFirstXxx, the more specific handlers registered by the DefaultColumnGroupHeaderLayerConfiguration are kind of overriden. To fix this the GroupByHeaderConfiguration now also registers the dragmode for the column group reordering.

Note: This only works for the new performance ColumnGroupHeaderLayer. The old implementation is deprecated.
