Browser support of width and height properties of getBoundingClientRect?

cross-browser, dom, getboundingclientrect, javascript

Solution

In IE9 as IE8:

document.body.getBoundingClientRect() 
[object] {
    right : 2556,
    top : 0,
    bottom : 1195,
    left : 0
}

In IE9 as IE9:

document.body.getBoundingClientRect() 
[object ClientRect] {
    bottom : 1435,
    height : 1435,
    left : 0,
    right : 2544,
    top : 0,
    width : 2544
}

So, I'd say yes on IE9, no on IE8...

Problem

I just discovered and really like `getBoundingClientRect` because it includes sub-pixel precision. This has allowed me to create consistent alignment, even if the user types Ctrl+ or Ctrl+-. It has properties `top`, `bottom`, `left`, `right`, & `width` & `height`. It is simple to find the browser support on the internet, but not so much for the the `width` and `height` properties in particular. It appears that this was added after the fact. It works in Firefox, Chrome, and IE10, but what about IE8 & IE9? I can't test these conveniently.
