  <meta name="assert" content="This test checks that if 'column-fill' is set to 'auto' and a multicolumn element content is solely made of block container boxes, then it should fill column boxes sequentially with such content and, in this test, it should overflow outside of it. This test relies on the idea that a 'column-span: all' element will occupy more space in a multi-column element than a 'column-span: none' element, therefore reducing available space for content in column boxes." />
