Indeed, blindly assigning to the “innerHTML” property is particularly 
problematic where the parser implementation is not stable, allows for 
proprietary extensions, or fragments from other markup languages can be 
embedded.

“g” is the name of an SVG element type [1], and a plain “<g>” tag will be 
parsed into an HTMLUnknownElement node by an HTML5-compliant parser.  The 
same parser will parse it into an SVGGElement node when it is located within 
“<svg>…</svg>”.

    [It is not possible to accidentally insert HTML elements or to insert
     SVG elements in an SVG document that way: the corresponding element
     objects do not have an “innerHTML” property.  Assigning to the
     “innerHTML” property of an SVG element object will either fail with a
     runtime error or create that String property on that host object,
     having no other effect.]

Tested in Chromium “22.0.1229.94 Built on Debian wheezy/sid, running on 
Debian 7.0 (161065)”.
