Any image/texture types that accept texture drops from content library will simply set the source to whatever the local bundle location of the texture is rather than importing the texture into the project and using that. When you drag textures into 3D models, the texture is imported first, so I would expect the same to happen in this case as well.

• Add Image element into the scene
• Drag a texture from content library into the image element in navigator. (download the texture first if necessary)

--> The Image source is set to point to the texture location inside the local bundle folder. The expectation is that the texture is imported into the project and the imported path is used instead.
