<pre>Reduced test case at <a href="http://codepen.io/pkra/pen/mEqOGx">http://codepen.io/pkra/pen/mEqOGx</a>.
It displays an "x" with a red background and next to it a span that has display:inline-block. Inside that inline-block are two spans with display:block, the second one being an "x" on the pink background, and the first a span with a thin height and green background. These should be stacked vertically, and the whole in-line block should be aligned on the baseline of the bottom span in the inline-block.
(The test case adds the computed values of bottom/height/offset for convenience.)
The expected behavior would be that the two x's should be aligned.
However, the two x's are not aligned.
This works as expected in Firefox and IE8+.
