<p>This tests whether an element's onclick attribute can be a function
named "OnClick". Some older versions of WebKit had a bug in the DOM
binding for Element that would prevent the function from being called
because we have an attribute of the same name.</p>
<input id="a" type="button" onclick="OnClick();" value="Don't Touch">
<p id="b">If you can read this, then the test failed!</p>
