Created attachment 423739 [details] testcase ###!!! ASSERTION: New (SVG > 1.1) SVG viewport establishing element?: 'Error', file /Users/jruderman/mozilla-central/layout/svg/base/src/nsSVGUtils.cpp, line 533
Created attachment 594620 [details] [diff] [review] Don't treat <svg:image> as a viewport establishing element. I think it makes sense just to have <image> not be considered to be a viewport establishing element. It does establish a viewport but for the referenced document, not child content in this document.

Comment on attachment 594620 [details] [diff] [review] Don't treat <svg:image> as a viewport establishing element. Yeah, agreed. Can you add an explanatory comment to nsSVGUtils::EstablishesViewport noting this though? (Maybe with a pointer to this bug.)
