jQuery SelectMenu not showing the selected item when using scroll bar in IE>9

Hi 
I am using jQuery select menu to display dropdown list. The drop down list has around 100 items. so i used to max-height to display some items and used scroll bar to go to see other items. when i am using the scroll bar the selected item is not displaying in IE9 and above. it is working fine in chrome.
you can use the following link in IE9 and above and find the observation.

in the above link go to select a number dropdown and select number 18. and click the drop down again the scroll is at first element.

please let me know how can i fix this issue in IE>9.

Thank you,
Ramana
