I have a ContentReference field with UIHint.Image set. In the CMS gui, when clicking on the button with the ellipsis on the right side of the field, the 'Select Media' box is shown where you can select the image. 
There's also a search box above the tree structure, where items show up as you start to type. 
When you click 1 of those results, nothing really happens. I would expect 1 of these things to happen:

1. the location where the chosen item is stored is opened in the tree structur inside the box, or:
2. the item is directly loaded into the underlying field and the 'Select Media' box is closed

To me, it looks like a bug, as you can't really do anything with the search results.
