Known "bug": translator will not work on PDF pages if those are accessed from
individual item pages. There does not seem to be any way to construct
metadata POST data from those views. If PDF is access directly from search
results, we can reconstruct necessary data from the URL.
We could try to go to a different page to fetch metadata
