See https://bugzilla.mozilla.org/show_bug.cgi?id=628747

If other browser vendors choose to expose their users to that sort of 
privacy leak, I guess that's up to them.  But the spec shouldn't 
recommend using this mode for things like <html:img> without 
highlighting the possible issues that result.

Did this never get brought up on this list?  The plan was to bring it up 
here...

OK.  Again, I have no problem with the mode existing so much (I can 
always just ignore its existence as an implementor); I have problems 
with the spec recommending, for reasons that are unclear to me, that 
animated SVG not be supported in CSS background images.
