P: Create Collection uses the wrong collection set when filtering in the Collections panel

When filtering in the Collections panel, right-clicking a collection set and doing Create Collection puts the wrong collection set in Inside A Collection Set.

To reproduce:

1. Make a new catalog.

2. Make two collection sets, XXX and YYY.

3. In the Filter Collections box, type YYY and then select YYY:

4. Right-click YYY and do Create Collection.

5. Observe that it incorrectly shows Inside A Collection Set: Smart Collections rather than YYY:

6. Clear the Filter Collections box, right-click YYY again, and do Create Collection.

7. Observe that it now correctly shows Inside A Collection Set: YYY.
