user modified materials are not saved

in the case of textures loaded in this way, the img element with the src and id attributes is added dynamically to the a-assets DOM element. When saving to JSON, only the id value is saved in material component. Then after loading the JSON file, there is no img with this id in a-assets, so the texture is not loaded.
A possible solution here is to store the src attribute instead of the id for the material texture in case the texture is loaded this way.
All that remains is to learn how to determine that a texture is loaded from external sources. This can be a check if the texture's src does not contain assets.3dstreet.app.
Another question - is it safe to use assets.3dstreet.app to check the source of assets? I think it's better to store the current assets URL address in one of the a-assets element attribute. Then it will be more reliable
