Improve SVG support in Blazor

Treating this as the top-level issue for SVG support in Blazor to track

SVG support has nicely been working for me until I started experimenting with foreignObject.

A possible workaround until "full support" is to render your problematic content as raw html using MarkupString:

<svg>
    @((MarkupString)$"<foreignObject>Hello, <em>{@name}</em>!</foreignObject>")
</svg>

@code {
    private string name = "World";
}

Hope it helps prevent a few headaches!

CultureInfo can interfere with SVG rendering, specifically which decimal separator is used. Probably quite tricky to handle, how to feed SVG properties (or CSS for that matter) with the expected number formatting while retaining Blazor ability to localize content? Important feature for full SVG support.
