  <meta content="This test checks that when the initial containing block's writing-mode is 'horizontal-tb' and its 'direction' is 'rtl', then an absolutely positioned box (with 'left' is 'auto', 'width' and 'right' are not 'auto') whose containing block is the initial containing block must solve for 'left'. Whether such absolutely positioned box's 'writing-mode' is vertical or not is irrelevant." name="assert" />
