Errors with 'mergedate' option in per-entry scope

[matteofg]

Below a mwe:

\begin{filecontents}[overwrite]{\jobname.bib}
@article{test1,
  author = {Doe, John},
  title = {Title of the Article},
  journaltitle = {Title of the Journal},
  date = {2023},
  options = {mergedate=minimum},
  %options = {mergedate=basic},
  %options = {mergedate=maximum},
}
@article{test2,
  author = {Doe, John},
  title = {Title of the Article},
  journaltitle = {Title of the Journal},
  date = {2024},
  options = {mergedate=minimum},
  %options = {mergedate=basic},
  %options = {mergedate=maximum},
}
@article{test3,
  author = {Doe, John},
  title = {Title of the Article},
  journaltitle = {Title of the Journal},
  issue = {spring},
  date = {2024},
  options = {mergedate=minimum},
  %options = {mergedate=basic},
  %options = {mergedate=maximum},
}
\end{filecontents}

\documentclass{article}
\usepackage[style=authoryear]{biblatex}
\addbibresource{\jobname.bib}

\begin{document}
\parencite{test1}
\parencite{test2}
\parencite{test3}
\printbibliography
\end{document}

• setting mergedate=minimum the option doesn't work fine about the 'test2' and 'test3' bibliography items;
• setting mergedate=basic the option doesn't work fine about the 'test3' bibliography item;
• setting mergedate=maximum the option doesn't work fine about the 'test3' bibliography item.

Thanks for reporting this. That was a stupid oversight that should be fixed in c9eec5b.
