I don't think this works in FF and Opera either.

It seems to load now, but with a wrong scale.

Intentionally so. In Firefox images must be self contained so <image> elements within SVGImage documents would need to be data URLs. See https://bugzilla.mozilla.org/show_bug.cgi?id=628747
Worth noting that WebKit does not work with data URLs or linked images. IE9+ and Firefox both work with data URLs and even IE9+ supports linked images.
Christian Schaefer was nice enough to point out that it does in fact work with Inline SVG.
Images are not allowed to load further resources. This is intentionally.
