This test passes if there is a horizontal green line below. It tests that:
<ul>
<li>a block setting white-space:pre does not affect the whitespace-collapsing
behavior of an inline setting white-space:nowrap</li>
<li>an inline setting white-space:normal or nowrap does not allow wrapping
when nested in a block that sets white-space:pre</li>
</ul>
<div class="test pre"><span>x xx</span></div>
