Steps to reproduce:
1. Create new Unity project using Universal 3D Template
2. Build project via Build Profiles window
3. Open Build Analysis window
4. Open Assets tab
5. Search “unity_builtin_extra” Asset and select it
6. Observe the Asset
Actual results: Selecting “unity_builtin_extra” in the Build Analysis Assets Table shows no "File Extension" data and clicking the "Select" button does nothing, the Asset is not highlighted in the Project window
Expected results: "File Extension" field is populated for unity_builtin_extra in the Asset Table and clicking "Select" highlights and navigates to the asset in the Project window, or, if the file is not accessible to users, it should not be listed in the Asset Table at all
