[Catalyst] CanMixGroups Set to False Still Allows Reordering Between Groups in CollectionView

[NafeelaNazhir]

Description

When the CanMixGroups property is set to false in the CollectionView, items can still be reordered between groups. This behavior is incorrect because setting CanMixGroups to false should restrict items from being dragged and dropped across groups.
Note: This Issue arises in both CV2 and CV1

Steps to Reproduce

1. Launch the application on catalyst CanMixGroupsSample.zip
2. Set the "CanMixGroups" radio button to False and set "CanReorderItems" to true.
3. Attempt to drag and drop an item from one group to another in the CollectionView.
4. Observe that the item is still moved across groups, even though CanMixGroups is set to false

Expected Behavior:
When CanMixGroups is set to false, the CollectionView should prevent items from being reordered between groups. Items should only be reorderable within their respective groups.

Actual Behavior:
Items can still be dragged and dropped between groups.
