Link to URL in PDF export of beamer or projector style not working

The link is clickable in TeXmacs and the preview but not in the PDF export. The problem occurs in the beamer and projector style but not in the generic style. Here is the minimal example.

<TeXmacs|2.1.1>

<style|beamer>

<\body>
  <screens|<\shown>
    <hlink|TeXmacs|https://texmacs.org/tmweb/home/welcome.en.html>
  </shown>>
</body>

<initial|<\collection>
</collection>>

This should be a bug. Better to submit a bug report.

This has already been reported:

@xuyiqi1 found that the problem maybe with the papyrus page rendering. Setting the page rendering to paper before the export, the link is clickable.

Interesting, thanks. That would be a good data point to add to the bug report.

If I remember correctly, exporting PDF for papyrus is buggy. I do not remember whether I reported that before.
