<pre>On a page like <a href="http://smfr.org/misc/four-bars-shadows.html">http://smfr.org/misc/four-bars-shadows.html</a>, if you zoom in and pan around, bits of the bars are sometimes missing.
This happens when they get into tiled mode, but we fail to update the tiles during scrolling.
This is related to <a href="https://trac.webkit.org/changeset/186155">https://trac.webkit.org/changeset/186155</a>.</pre>
