This tests that the SVGLoad event does not bubble.
After loading the tests, two rectangles are displayed. The left rectangle indicates whether the SVGLoad event dispatched to the root 'svg' element did not bubble and the right rectangle indicates whether the SVGLoad event dispatched to an 'image' element did not bubble. Each rectangle is red if the sub-test failed or green if it passed.
Run the test. No interaction required.
The test is passed if both rectangles are green once the document has loaded.
