By default the \cite command ignores a semicolon if it follows a dot. How can I force biblatex to print the semicolon regardless if there is a dot before?
\documentclass{article}
\usepackage[
style=authortitle,
backend=biber,
]{biblatex}
\begin{filecontents*}{\jobname.bib}
@book{test,
author = {Foo, Bar},
title = {Foobar},
year = {2016},
location = {Baz}
}
\end{filecontents*}
\addbibresource{\jobname.bib}
\begin{document}
\footnote{\cite[12]{test}; \cite[12~f.]{test}; \cite[12~ff.]{test}}
\end{document}
(And yes, I know that in general I should use \cites. But for technical reasons I cannot in this case.)
