Anchor links do not work in PDF exports

Anchor links do not work in the PDF export version of a page.

Steps to reproduce:

1. Create a page with anchor link(s) to any page within the same Confluence instance, ideally by adding it from Recently Viewed pages. Optionally you may want to add external links, to verify those work fine.
2. Save the page.
3. Click on Tools > Export to PDF
4. The PDF will contain all the links, however the anchor links will only be visible as links (blue, underlined), but non-clickable.

Example page source:

<p>Anchor link:</p>
<p>
  <ac:link>
    <ri:page ri:content-title="Tutorial"/>
  </ac:link>
</p>
<p> </p>
<p>External link:</p>
<p>
  <a href="http://www.atlassian.com">http://www.atlassian.com</a>
</p>
