when copying assessable course elements such as test or SCORM within a course, already referenced learning resources are not copied alongside the node and its settings.
non-assessable elements such as wiki or blog are always copied with their reference to a learning resource.
this is not comprehensible for authors, and should be changed into a uniform behaviour. Therefore, references should also be copied for assessable elements.
Listing of course with multiple references does not have to reflect the correct number of references in information panel (select learning resource in element), but needs to be listed as long as a single reference exists.
