            Bug ID: 145363
           Summary: Web Inspector: Uncaught exception in when using
                    Inspect tool on SVG elements
    Classification: Unclassified
           Product: WebKit
           Version: 528+ (Nightly build)
          Hardware: All
               URL: http://cse512-15s.github.io/a3-adityas-burg-aburner/da

                OS: All

Steps to repro:

1. Go to the URL.
2. Inspect any SVG element with the "Inspect" picker. The numbered circles are an easy target.

At this point, the 1st level inspector debugger pauses, with message:

Exception with thrown value: TypeError: node.className.trim is not a function. (In 'node.className.trim()', 'node.className.trim' is undefined)

It seems that InjectedScript.prototype._nodeDescription is blowing up because SVG*Element.className will return an SVGAnimatedString instead of a DOMString.
