I'm not 100% sure about this, but as per my reading of http://dev.w3.org/csswg/css3-writing-modes/#orthogonal-flows, we do the wrong thing with the following case:
<div style="height:300px; -webkit-writing-mode: horizontal-tb">
    <div style="height: auto; -webkit-writing-mode: vertical-rl; border: 1px solid">asdf</div>
</div>

The physical height of the inner div should be shrink-wrapped to it's content, instead it's 300px.

Am I misreading the spec? Is the spec stupid?
