The assertion holds if the larger green block is on the left.
- The test consists of two divs, one inside the other, and drawn over the same space. The outer has a RTL direction, the inner, LTR. The outer div has margin-left and margin-right set to large and small values, respectively. The margins of the inner div should show as a green block around the yellow core. To match the assertion, the wider green block should be on the left, since that's where the inline-start is for a LTR block.
