Additional context

Source

This PDF is build from the following LaTeX code:

\documentclass{amsart}

\usepackage{hyperref}

% Macro to use same adress for \email and href example
\newcommand{\myemail}{john.doe@faculity.uni-cityname.tld}

\title{email in amsart}
\author{John Doe}
% Second email address  with the problem comes from here
\email{\myemail}

\begin{document}
    \maketitle  

    % First email address inside the PDF (for comparision) this one works fine
    email link in the text body: \href{mailto:\myemail}{\myemail}

\end{document}

Other PDF Viewers

• VSCodium and Obsidian behaves the same, but I think they are using PDF.js.
• KDE Okular only shows a mailto link for the first email address.
• Chromium (with the default PDF viewer, I think that is pdfium) shows mailto links for both email addresses without problems.

If you think the second mailto link in the PDF file is broken in any way, an explanation with details (and a possible reason why some other viewers have no problems with it) would be helpful. Then I would report the bug to the LaTeX class maintainers.

Without a dot between @ and dash

In case of an email address without a dot between the @-Symbol and the dash, PDF.js does not show any mailto link for the second email address. Example with john.doe@uni-cityname.tld instead of john.doe@faculity.uni-cityname.tld: mail-test.pdf

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.
