<p><b>BUG ID:</b> <a href="https://bugs.webkit.org/show_bug.cgi?id=41113">Bugzilla bug 41113</a> [WinCairo] Text box backgrounds do not render in partially opaque layers</p>

<div style="background-color:skyblue; padding:3px;">
In the next paragraph you should see a partially opaque sequence including:
<ol>
<li>The word "Before"</li>
<li>A text box</li>
<li>The world "After"</li>
</ol>
If this test is failing you will not see the text box border.
