I'm calling getComputedStyle on an element that defines `left`, `right` and `bottom`.

In Chrome this returns `'auto'` as the value for `top` but in Firefox this returns the pixel value, however if you look at the inspector in Firefox the `top` value doesn't show up in the computed pane.

Is there any way to workaround this? Here is a fiddle showing the issue <http://jsfiddle.net/DEfusion/9NaGD/>
