Links won't open from a PDF file

Steps to reproduce
1. Open a PDF file that includes links to editable documents (ex: odt)
2. The opening of the document is blocked because Chrome / firefox detects that it is opened from an iframe (default browser PDF viewer)

Expected behaviour
Allow the opening of the document or if not possible force owncloud to download it because the links work when cliked from the defaut desktop pdf reader

Thanks !

When creating such issues the absolute minimum is to provide the running oC version...
