https://commons.wikimedia.org/wiki/Template:Cc-by-sa-layout and possibly other license templates contain extra whitespace and in particular line breaks in the HTML-based license metadata. The "Use this file" function includes these linebreaks in the generated embedding HTML, which then doesn't work correctly (the license isn't linked). For https://commons.wikimedia.org/wiki/File:Saint-Pierre-de-M%C3%A9sage_%2838%29_-_Salle_des_f%C3%AAtes.jpg#mediaviewer/File:Saint-Pierre-de-M%C3%A9sage_%2838%29_-_Salle_des_f%C3%AAtes.jpg The HTML generated is <p><a href="https://commons.wikimedia.org/wiki/File:Saint-Pierre-de-M%C3%A9sage_(38)_-_Salle_des_f%C3%AAtes.jpg#mediaviewer/File:Saint-Pierre-de-M%C3%A9sage_(38)_-_Salle_des_f%C3%AAtes.jpg"><img alt="Saint-Pierre-de-Mésage (38) - Salle des fêtes.jpg" src="https://upload.wikimedia.org/wikipedia/commons/2/20/Saint-Pierre-de-M%C3%A9sage_%2838%29_-_Salle_des_f%C3%AAtes.jpg" height="960" width="1280"></a><br>"<a href="https://commons.wikimedia.org/wiki/File:Saint-Pierre-de-M%C3%A9sage_(38)_-_Salle_des_f%C3%AAtes.jpg#mediaviewer/File:Saint-Pierre-de-M%C3%A9sage_(38)_-_Salle_des_f%C3%AAtes.jpg">Saint-Pierre-de-Mésage (38) - Salle des fêtes</a>" by <a href="//commons.wikimedia.org/wiki/User:Parisdreux" title="User:Parisdreux" class="mw-redirect">Parisdreux</a> - <span class="int-own-work">Own work</span>.

While this could be fixed in the templates, I think it'd be better to fix this in the MediaViewer by doing a trim() of the extracted metadata.
BTW, it'd be very nice if the MediaViewer would just generate the links back to the file as https://commons.wikimedia.org/wiki/File:Saint-Pierre-de-M%C3%A9sage_(38)_-_Salle_des_f%C3%AAtes.jpg instead of https://commons.wikimedia.org/wiki/File:Saint-Pierre-de-M%C3%A9sage_(38)_-_Salle_des_f%C3%AAtes.jpg#mediaviewer/File:Saint-Pierre-de-M%C3%A9sage_(38)_-_Salle_des_f%C3%AAtes.jpg

(In reply to Andre Klapper from comment #3) > That is covered in bug 62266 instead. I don't understand. Bug 62266 is about browser history, not about the backlink generated into embeddable HTML.
Does MediaViewer use the extmetadata API? If so, this bug should probably moved to the MediaWiki API component: https://commons.wikimedia.org/w/api.php?action=query&prop=imageinfo&iiprop=extmetadata&format=jsonfm&titles=File:Saint-Pierre-de-M%C3%A9sage%20%2838%29%20-%20Salle%20des%20f%C3%AAtes.jpg returns: "UsageTerms": { "value": "Creative Commons Attribution-Share Alike 3.0\n", "source": "commons-desc-page", "hidden": "" }, "LicenseUrl": { "value": "http://creativecommons.org/licenses/by-sa/3.0\n", "source": "commons-desc-page", "hidden": "" }, Again, note the line breaks in the values.
