In current versions of Magento (Community Edition, at least), Prototype messes with the Array prototype. As a result, the part of SVGInjector that copies attributes of the original `img` tag to the newly embedded SVG `tag`. The fix is manually iterating over the `img` tag's attributes instead of using `Array.filter()`, and adding the attributes matching the pattern to `imgData`.

I agree. But since prototype.js' last release was in September 2015 I doubt they will fix anything. Also, fixing this in prototype.js is not backward compatible. The proposed change here on the other hand is completely transparent. |

The method
Array.prototype.filter()is overridden by prototype.js, changing the semantics of the call, which triggers an exception and essentially breaks SVGInjector on any site that uses at least version 1.7 of this library.A test case that breaks without the fix is included.
Since there are no contribution guidelines, I was not sure whether to do take the steps of the release procedure into this pull request. Please advise.
