Comment 67 for bug 747197

I'm nominating this for 1.6 because I think saving web pages is a fairly common
task and as CSS becomes more prominent, we're seeing more and more pages that
don't save completely. dbaron thinks this might be more 1.7alpha material but it
does cause one of our smoketests, B.27, (and I suspect an increasingly
representative smoketest) to partially fail.
