Enable navigation back to article landing page

[mfelczak]

Hi @asmecher, one of our hosted clients recently reported that the browser back button no longer works after a reader clicks on one of the Lens tabs (e.g. Figures). As a result, it's not possible to return to the article landing page. Would it be worthwhile to add a header above the Lens Reader similar to the PDF viewer that includes additional navigation elements, i.e. back arrow, article title?

@mfelczak, there's a suggested Lens modification that can accomplish this: https://forum.pkp.sfu.ca/t/ojs-3-lens-reader-needs-a-back-button/23952/4
