Links within a PDF file don't work

Links within a document (with href="#element-id") are not converted to internal PDF links correctly.

Example of a document:

<p id="page1">
  <a href="#page2">Link to page 2</a>
</p>

<p id="page2" style="page-break-before: always">
  <a href="#page1">Link to page 1</a>
</p>

This is locale-independent issue (unlike the previous one).
