This test tests that an element with the name 'listener' is not interpreted as an svg element,
and that it's not the same as an element named 'listener' in the XML Events namespace.
The test has passed if handlers are implemented (the handler with xml:id="passhandler" has run)
but the handler with xml:id="failhandler" has not run.
If the handler is run then the text in the testcase will show "Test failed: 'listener' is not an svg element.".
The pass condition is indicated by two rects that must both be green after running the test, if
either of the rects is red then the test has failed.
