Version First 25.12.2

example PDF
SUMMARY
Some email addresses in PDFs files do not show a mailto: link, but other PDF
viewers like PDF.js do.
STEPS TO REPRODUCE
1. Open in okular the example PDF from the attachment (or build it yourself see
ADDITIONAL INFORMATION)
2. Hover with your mouse over the two email addresses in the document.
OBSERVED RESULT
Only the upper email address shows a mailto to link in the hint, which can be
clicked.
EXPECTED RESULT
Both email addresses in the document show a mailto link in the hint, which can
be clicked.
SOFTWARE/OS VERSIONS
Linux/KDE Plasma: Manjaro Linux
KDE Plasma Version: 6.5.5
KDE Frameworks Version: 6.23.0
Qt Version: 6.10.2
ADDITIONAL INFORMATION
The second email address in the document seems to be somehow different. If the
address contains a dash, PDF.js had also problems with it in a previous
version. In the issue there a developer explained the different between the two
email addresses (maybe that is helpful):
> It looks like a bug in the autolinker. The first occurrence that is rendered
> correctly is a link annotation inside the PDF file, while the second link
> that is not rendered correctly is a link that is inferred from the text
> content.
