I've used interactive SVGs with ox-html output quite a lot, and I found it
necessary to add the following horrible code; I'm not sure it's still
required:

----
    let svgdoc = object.contentDocument;
    let svgid = object.id;

    if (!svgdoc) {
        if (object.parentNode /* XXX why is this necessary */)
            object.parentNode.innerHTML = "";
        return;
    }

    let found = false;
    for (let el of svgdoc.getElementsByTagName("svg")) {
        let width = el.getAttribute("width");
        let height = el.getAttribute("height");

        let width_pt = width.match(/^([0-9]*)pt$/)[1];
        let height_pt = height.match(/^([0-9]*)pt$/)[1];

        let width_px = 5/4 * width_pt;
        let height_px = 5/4 * height_pt;

        object.setAttribute("width", width_px + "px");
        object.setAttribute("height", height_px + "px");
        found = true;
    }
----

In my case, the SVG was produced by graphviz, so it always has the width
and height attributes.

This is a minor issue, but I also think the fallback message ("Sorry, your
browser does not support SVG.") is really horrible and misleading. It's
very unlikely to be a browser issue today, and much more likely to be a
missing file or a user deliberately disabling SVG. In that case, software
shouldn't say it's sorry :-)

"Cannot load SVG file." would be a better message, I think.
