I appreciate the "field reports!" They prompted me to look closer, and I have found more specifics about this issue. It is also not nearly as bad as I thought.
In the Media Pool, typically I select the parent folder, as well as the first child folder. This shows me all shots in all child folders. [

If I directly select all folders [

So I guess this is less of a "bug" and more of a "change in behavior."
