jQuery autocomplete menu list display issue with Google Chrome
===

I'm using jQuery UI autocomplete (with multiple value support) and encountered on a problem displaying the menu list. The interesting thing about this issue is that I only encounter it in Google Chrome (20.0.1132.47) but not in Safari (5.1), and Firefox 12 (don't know with IE, haven't tested on it yet).

You can check out this behavior by rendering the sample code from this [jsbin page](http://jsbin.com/ahegoj/3/edit#javascript,html). The sample code I created makes use of the jquery autocomplete which will list down various names of programming languages for the first value entry, and list of versions for the next entry.

The issue occurs when I make a selection from a long menu list that displays a vertical scrollbar, and then do another selection with a shorter list. Here's how to replicate the issue in google chrome using the sample code:

1. Press key down and then select any options between "ActionScript" and "BASIC". 
2. Press key down again and you will see 1-3 list options. This is the expected result.
3. Remove the entries from the text box. 
4. Press key down and then select "C" option by scrolling down in the list.
5. Press key down again and you will see only 2 and 3 menu list options, with 1 missing and with 2 not shown in full.
6. Selecting any other options starting from "C" downwards will even make the menu list for the next selection more erroneous.

My question: Is there a way to get a workaround on the autocomplete menu list display behavior in Chrome?
