+<p>Test adding an ::after pseudo element that's a spanner. The DOM node is followed by more content,
+ so we need to split the existing column row into two.</p>
+<p>There should be three rectangles with identical sizes below. The first and third one
+should be blue with nothing inside. The second one should be yellow with some dots
+inside.</p>
