When an HTML <iframe> points to an SVG file, typically the contents of the SVG file are scaled to fit the frame (assuming the viewBox is set and width/height are 100%). However, when applying page zoom it seems that both the frame and the contents are zoomed separately and hence the contents no longer fit the frame.

Appears to be a regression. Works fine with ESR 10.

Comment on attachment 8776620 [details] [diff] [review] We should treat an iframe the same as object, embed etc. Thanks, Robert! Would you be able to add a reftest for this in layout/reftests/svg/moz-only? I think you can set reftest-zoom="2" or something on the <html> element to trigger zoom.
