Resolved value (getComputedStyle) of "top" isn't computed correctly

[eefriedman]

<div style="position: absolute; padding: 30px;">
<div style="opacity: 0.5; background-color: green; padding: 10px">
<div id=cool style="position: absolute; top: 0;"></div>
</div>
</div>
<script>
alert(getComputedStyle(document.getElementById("cool")).top);
</script>

The obvious value for top is 0px; Servo comes up with -30px because it's computing the position relative to the stacking context, not the absolute containing block.

getComputedStyle is pretty complex and isn't specced in much detail =/

This is still true.

Not sure what the correct answer is supposed to be, but I get -38px currently
