<p>Changing a collapsed border's width should change the width of the table and the width of a shrink-to-fit containing block.</p>
<p>There should be a square with a 4px inner blue border and a 1px outer black border.</p>
<p>Firefox 50.0a1 (nightly 2016-07-07) fails this, so it should probably be upstreamed, except it uses chrome-specific `runAfterLayoutAndPaint`.</p>
<p>The table cell has rowspan=2 because we almost didn't cover the case where a cell's rowspan exceeded the declared rows.</p>
