[Reader] Navigate references in new pdf reader

Hi,

it would be great if you could come up with a good way to navigate reference links in a paper.
Currently the navigation seems to be broken and the hyperref links lead nowhere.
My conception of a good referencing experience would be something like semanticscholar.org has in its reader, where the reference is displayed on the page when clicking on the hyperref link.
Is the implementation of the reader available somewhere as open source?

Cheers

The issue names no files, tests, or entry points, and says the reader implementation may live elsewhere. First locate the new PDF reader and its hyperref/reference-link handling in the implementation repository. Done means clicking a reference displays or navigates to the cited reference on the page instead of leading nowhere, with behavior comparable to the described Semantic Scholar reader.
