Presentation’s PDF exports break some external links

[Chouhartem]

Description

When exporting PDFs, external links are not working. The behaviour of the links depends on the PDF viewer.

A minimal example can be found here with the resulting PDF.

You can notice in the CryptPad presentation app that Ctrl + Left Mouse Button gives you the website of the CryptPad project on both links.

Now, if you export it, you can realise that, on the resulting PDF:

• In firefox, only the second link is clickable (and working)
• In chromium, both links are “clickable” but don’t do anything
• In evince, okular and zathura: both links link to an empty string

Steps to reproduce

1. Create a presentation
2. Embed a link on a text by right clicking then “⛓️Hyperlink” and add a link
3. Add an automatic link (e.g. typing https://cryptpad.org/ and add a space or a new line afterward)
4. Export the PDF

• Either by printing the file
• Or with File > Export > .pdf

5. Notice that links are broken

Expected behavior

The links should be preserved upon exporting.
