Actually, that depends.

Compare the offsetTop/offsetLeft of #x from

<!doctype html>
<style>
  body { margin:0 }
  div { border:10px solid; height:100px; width:100px }
  div#x { border:20px solid orange; height:10px; width:20px }
</style>
<div><div id=x></div></div>

with

<!doctype html>
<style>
  body { margin:0 }
  div { border:10px solid  }
  div#x { border:20px solid orange; height:10px; width:20px }
</style>
<div><div id=x></div></div>

in Internet Explorer.

Since Firefox and Opera always are relative against the border box I think  
reverting this was a mistake. This is exactly the hasLayout dependency I  
was trying to avoid.

Or am I missing something?
