the server does not send Content-Encoding: gzip... this looks invalid to me.

cc'ing bz who is into these things. Or at least knows about them...

[Boris Zbarsky [:bzbarsky]]

Yep, this is invalid.  The server claims that this is an image/svg+xml with no
encoding applied.  image/svg+xml is using the "+xml" suffix, so must be XML.  So
we parse it as XML.

The SVG Working Group is working on sorting out this mess, but as things stand
doing anything other than what we do would be a violation of existing finalized
standards.
