     Test for <i><a href="https://bugs.webkit.org/show_bug.cgi?id=19525">https://bugs.webkit.org/show_bug.cgi?id=19525</a>
     -webkit-box-reflect in hyperlink causes webkit to crash</i>.
 </p>
 <p>
     Because it is an inline flow, <span id="span" style="-webkit-box-reflect: below;">this span</span> should not have a reflection, and selecting it should not cause a crash.
