This test checks that an attribute is not removed when set to the initial value of an &lt;input&gt; tag
using <span style="font-family: monospace;">setAttribute()</span>.
If the test passes, you will see a list of <span class="pass" style="font-family: monospace;">PASS</span>
lines below, followed by <span class="pass" style="font-family: monospace;">TEST COMPLETE</span>.
See <a href="https://bugs.webkit.org/show_bug.cgi?id=4059">Bugzilla Bug 4059</a>
Some values used with setAttribute() cause the attribute to be removed (null strings vs. empty strings).
