Polymer makes getScreenCTM() crash

[jorgehatccrma]

When including polymer in a web page, the SVGElement getScreenCTM() method crashes with the following stack trace:

TypeError {stack: "TypeError: Illegal invocation↵    at b.<anonymous>…auser/libs/polymer.min.js:32:25185)"}
 "TypeError: Illegal invocation
    at b.<anonymous> (http://localhost/~auser/webCompTest.html:20:27)
    at v (http://localhost/~auser/libs/polymer.min.js:32:26221)
    at t (http://localhost/~auser/libs/polymer.min.js:32:25576)
    at r (http://localhost/~auser/libs/polymer.min.js:32:25321)
    at SVGRectElement.q (http://localhost/~auser/libs/polymer.min.js:32:25185)" polymer.min.js:32

I'm running Google Chrome 31.0.1650.48 on Mac OS X 10.7.5.

The bug can be reproduced with this gist. If the offending line (line 6) is commented out, the code works ok, but if polymer is included (even without "using it"), the code crashes with the afore mentioned trace.

@arv This looks like a ShadowDOM Polyfill issue.

Works for me
