Comment (by mcs):

 Replying to [comment:14 gk]:
 > Do we expect to get the external file type download dialog if SVG can't
 get rendered? See: https://upload.wikimedia.org/wikipedia/commons/6/6c
 /Trajans-Column-lower-animated.svg. If so, what happens if there are
 numerous of these things embedded in websites? Do users get then dozens of
 such dialogs? That would be suboptimal, I guess.

 Yes, for each top-level SVG document that is loaded and for each that is
 in an iframe, an external file download prompt will be displayed. I don't
 think it is common for web pages to use a lot of SVG images in that way,
 but I do not know for sure. Use of <svg> tags inline will not cause a
 prompt to be displayed.
