<p>Test for Bugzilla <a href="https://bugs.webkit.org/show_bug.cgi?id=86885">Bug 86885</a>: CSS2.1 failure: border-conflict-element021a.</p>
<p>When two adjacent table row groups (thead, tbody, tfoot) have the same border-width and the same border-style in a 'border-collapse: collapse' table, then the color of the border from the topmost table row group wins: so, a thead wins over a tbody which wins over tfoot.</p>
<p>This test verifies the aforementioned sceanario when more than one header and/or footer is specified. The first thead specified in the page should be rendered at the top of the table; similarly the first tfoot specified in the page should be rendered as the last section of the table. In this case both the top-most and the bottom-most sections should be displayed in green color. Also, there should be no overlap of border-colors at the corners.</p>
