// FIXME(drott) crbug.com/627143: We still have the issue of matching
// family name instead of postscript name for local fonts. However, we
// should definitely not try to take into account the full requested
// font description including the width, slope, weight styling when
// trying to match against local fonts. An unstyled FontDescription
// needs to be used here, or practically none at all. Instead we
// should only look for the postscript or full font name.
// However, when passing a style-neutral FontDescription we can't
// match Roboto Bold and Thin anymore on Android given the CSS Google
// Fonts sends, compare crbug.com/765980. So for now, we continue to
// pass font_description to avoid breaking Google Fonts.
