Thanks for the prompt feedback, good to hear this!
It may not be so common for users to end up on media pages wihtout going through the item page, but it is a distinct possibility, somewhat facilitated by the popup in the Mapping module, but also through a number of other ways (search engines, direct shares, etc.).
Ultimately, given that a media is always related to an item, I struggle to see a use case when one would not want to have a reference to the item from the relevant media, even a basic “Go (back) to item”, or a “Media associated to item: {clickable item title}”, or something like that.
Thanks again!
