Misbehaviour when subfiles is used with standalone

[markellos918]

Inputting a tex file in a subfile when the standalone package is loaded causes the appearance in the pdf (of both the subfile and the master file) of a text string containing excerpts of the path. This is related to the presence of spaces in the folders names.

Files are organised as follows:

master.tex         sub folder_space/input.tex         subfolder_nospace/input.tex         subfiles/space.tex         subfiles/nospace.tex

master.tex:

\documentclass{book}
\usepackage{subfiles}
\usepackage{standalone}
\usepackage{lipsum,}

\begin{document}

\subsection*{The input file is in a directory containing a space in the name but is not called form within a subfile}
\input{"sub folder_space"/input}
\subfile{subfiles/space}
\subfile{subfiles/nospace}

\end{document}

Both input files: \lipsum[1]

subfiles/space.tex:

\documentclass[../master]{subfiles}
\begin{document}

\subsection*{The input file is in a directory containing a space in the name}
\input{../"sub folder_space"/input}
\end{document}

\end{document}

subfiles/nospace.tex

\documentclass[../master]{subfiles}
\begin{document}

\subsection*{The input file is in a directory NOT containing a space in the name}
\input{../"subfolder_nospace"/input}
\end{document}

\end{document}

In the pdf this is the string that shows up: folder ̇space/input.texfolder ̇space/input.tex. Please notice the high dots. The issue only occurs with subfiles >1.6 (in my test 2.2).
