image zoom for inline SVG

[pkra]

The new zoom is a great addition. However, it seems to only work for img tags.

For SVG, inline markup offers many benefts (e.g., using CSS and currrentColor to adjust for color modes, providing explorable descriptions).

It would be great if there was a zoom for these as well.

I realize that the interconnection to the document makes this harder (e.g., document CSS, use elements). But since the footnote pop-out seems pretty good at this kind of thing I'm hoping this wouldn't be too difficult.
