1608100 - Distinguish (in console log messages) between failure to start font download at all vs download that fails

Status: RESOLVED FIXED

(Core :: Layout: Text and Fonts, defect, P3)

Description

[Jonathan Kew [:jfkthame]]

Just a trivial thing: while looking at the failure in bug 1607000, I noticed that the user-font code issues a "download failed" console message from a couple of different stages in the process: either when UserFontSet::StartLoad() immediately returns an error without creating a network channel, e.g. due to mixed-content blocking, or if the channel is created successfully but subsequently returns an error.

To aid diagnosis of @font-face issues, I'd like to distinguish between these two cases, so that it's easier to see (just from the web console) what kind of failure is occurring.
