IE Edge Performance Issue when creating InfoBubble

[kunalgithub]

I am creating multiple markers with InfoBubble on the page using a for loop.

I saw in Chrome that InfoBubble takes around a millisecond to create on an avaergae.

But on IE10 , IE Edge - it takes on an average 60 ms .

Here is the sample :
var infoBubble = new InfoBubble( {
content : someHTMLString
minWidth : 310,
backgroundColor : 'rgb(1,89,68),
borderRadius : 0 ,
borderWidth : 0 ,
backgroundClassName : 'branch_bubble_data',
disableAutoPan: false,
maxHeight : 200
})

I can confirm a real performance issue, I am getting 15 - 50 times longer scripting time on IE compared to Chrome.
It seems to be the clientHeight call on the browser in the positionCloseButton function, see http://i.imgur.com/4vswcLY.jpg
