Comment 5 for bug 795387

Cheers Huw. Another prototype for you:

4. warning.message.not-on-h2.width:auto.png

   .warning.message forces a 30em width, so I've added a width:auto to
   the div on the message here. Fwiw, warning.message.not-on-h2.png is
   what it looks like with the 30em width.

I think that looks good, but part of me feels that the warning
triangle should be associated with the "Series initialization has
failed" text.
