 Tests that the onchange event can be set on any element with an attribute.
 
 On success, you will see a series of "PASS" messages, followed by "TEST COMPLETE".

I think this regressed with https://trac.webkit.org/changeset/231456/webkit

The test failed consistently when that change was first landed and passed after it was rolled out.

Probably caused by the test that runs before this one. Given the URL, I suspect one of those 2:
LayoutTests/fast/events/form-iframe-target-before-load-crash.html:        <form id="form1" style="display:none" method="post" target="test" action="http://anything.com"></form>
LayoutTests/fast/events/form-iframe-target-before-load-crash3.html:        <form id="form1" style="display:none" method="post" target="test" action="http://anything.com"></form>
