When adding a discID from a CDStub, if it finds a possible match in MB, it will display it under "Possible Mediums" and allow to attach the discID to it. Unlike in the search results, here we have no option to click on "show tracklist" - the discID must be added blindly. It'd be nice to fix it, especially if we want to make CDStubs more visible.

The same happens anywhere we use cdtoc/list ("Matching CDs" under disc lookup, and the cdtoc index page).
