<h1>Visibility collapse</h1>
<a href="https://drafts.csswg.org/css-tables-3/#computing-the-table-width">Spec</a>
<p>
When a row is collapsed, a cell spanning the row may get clipped. When the row is then uncollapsed,
the browser should not crash because the cell's children should be correctly updated and laid out.
</p>
<table>
  <tr>
    <td><div style="width: 10px; height: 10px"></div></td>
    <td rowspan="2">
      <div style="outline: 1px solid cyan">
        Overflow Overflow Overflow</div>
    </td>
  </tr>
  <tr id="rowToCollapse">
    <td><div style="width: 10px; height: 10px"></div></td>
  </tr>
</table>
