+    <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>

+            </x-td>
+            <x-td>
+                <span></span>
+            </x-td>
+        </x-tr>

+    When row group is collapsed, visible rows within the row group are still collapsed and therefore invisible.
