Cannot drag prefab from custom package

I cannot drag prefabs from a custom package into my scene (see gif), or into my Assets. Similarly, I cannot drag fbx assets.



Is this a bug? I would like to be able to distribute prefabs for my team to use via Unity Package Manager.

I have been directed to post here by @okcompute_unity from this thread https://forum.unity.com/threads/samples-in-packages-manual-setup.623080/

 

Is not being able to drag from Packages to Assets specific to Prefabs and FBX files, or does it apply to all assets that are not scripts, like Materials, Textures, etc?

 

@runevision I cannot drag materials and textures either

 

All right, thanks for checking it. I can see the discussion is continuing in the original thread, that's good.
