    <p>Test for bug <a href="https://bugs.webkit.org/show_bug.cgi?id=87900">87900</a>: Add support for direction on table row group with collapsing borders</p>
    <p>This test checks that a table with a vertical writing mode and a rtl row group properly compute its collapsing borders when the left borders are disabled.</p>
    <p>For this test to pass, there should be only green borders on the cells and no left border on the table.</p>
