#1049 make preview possible when using \graphicspath{{Pictures/}}

[Anonymous]

If I use \includegraphics[width=0.8\linewidth]{Pictures/picture.png}, it shows a preview of the png-file when I hover with the mouse over the command.
If I use \graphicspath{{Pictures/}} and \includegraphics[width=0.8\linewidth]{picture.pdf} the preview is not working. Could you make a preview in such a case possible as well? Thank you very much.
