Now, it shows just something like "Roboto - 6glyphs".
In terms of bug triage, this isn't enough information to understand what happens in a user's environment.

Firefox provides more useful information in its Inspector Fonts view, e.g.
> Roboto remote
> http://<actual url...> (woff)
> ...

If possible, showing remote/local, and actual font file path for remote fonts would be very useful especially in cases using Google Fonts or similar service.
