Converting PDF to image via Inkscape breaks fonts

I want to convert a PDF page to a PNG image. Following this answer, I tried the following command:

inkscape <PDF PATH> --export-dpi=300 --export-area-drawing --export-background=#ffffff \    --pdf-page=<PDF PAGE NUMBER> --export-filename="<IMAGE PATH>"

However, any fonts the PDF uses that aren't installed on my system are turned into a default sans serif font in the output image.

Is there a way to make Inkscape use the fonts embedded in the PDF?
