The issue was not related to WebView loading and rendering the SVG properly, it did.  The issue is that it is currently impossible to make a WebView with a transparent background unless you use reflection and hack it.  E.g.:

Field f = engine.getClass().getDeclaredField(“page”);
com.sun.webkit.WebPage page = (com.sun.webkit.WebPage) f.get(engine);

There is already a JIRA issue for this: JDK-8090547

That severely limits the ability to show SVG images in the UI.  Given the prevalence of high DPI displays and the need to render images at various sizes, I think it would be great to have SVG image support in an ImageView instead of hacking it via a WebView (even if under the hood the WebEngine does the rendering).
