The solution of moewe to the question Biblatex: Two bibliographies with different styles and sortings II Part 3 produces the desired output. Unfortunately, there is a special case where the output differs from the "normal" behavior.
Problem source: It seems to be the replacement of the \space with \addthinspace (\renewcommand*{\multicitedelim}{\addsemicolon\space} with \renewcommand*{\multicitedelim}{\addsemicolon\addthinspace}).
Problem: Long citations of several lines (multiple authors all in alpha style) with, for instance, \cite overflow the text margins when using the above-mentioned solution with \addthinspace.
Question: Is there a solution adding short/thin spaces instead of normal spaces?
Output with \renewcommand*{\multicitedelim}{\addsemicolon\space}
Output with \renewcommand*{\multicitedelim}{\addsemicolon\addthinspace}
