Not sure if this is a bug or a feature. Repro steps:
- Starting a new Blueprint 3rd Person Game
- In the Content Browser expand one of the folders that has another folder inside, select that “child” folder.
- Click the folder arrow to collapse the folder(s) underneath the parent
- The Content Browser displays a ton of C++ classes in addition to the asset included with the 3rd person game.
It seems like it should select the parent folder that you just collapsed rather than everything.
