LayoutTests/fast/text/whitespace/nowrap-line-break-after-white-space.html

<p>
    This tests that <tt>-webkit-line-break: after-white-space</tt>
    trailing space truncation is not applied to text that does not auto-wrap.
</p>
<p>
    This box should have an active horizontal scrollbar, allowing the text to
    be scrolled to the left, making the trailing space on the right visible.
</p>
