+  <meta content="This test checks that when a clearing element (in a block formating context with 'writing-mode' set to 'vertical-rl') has a right margin larger than the width of a floated element, then the right margin is collapsed with the margin-left of preceding in-flow sibling. The clearing element is then placed at the point of the resulting collapsed margin." name="assert" />
