    <a href="https://drafts.csswg.org/css-tables-3/#computing-the-table-height">Spec</a>
    <p>
    Collapsing a row group but making its rows visible should still result in a
    collapsed row group.
    </p>
    <x-table id="one">
      <x-tbody>
        <x-tr>
            <x-td>
                <span>row 1</span>
            </x-td>
            <x-td>
                <span></span>
            </x-td>
        </x-tr>
        <x-tr>
            <x-td>
                <span>row 2</span>
            </x-td>
            <x-td>
                <span></span>
            </x-td>
        </x-tr>

            <x-td>
                <span></span>
            </x-td>
        </x-tr>
    </x-table>
    When row group is collapsed, visible rows within the row group are still collapsed and therefore invisible.
