Multi value control resizing issue in TFS2013.2

Hi, We've recently updated TFS 2013 to [TFS 2013 Update 2](http://blogs.msdn.com/b/bharry/archive/2014/04/02/tfs-2013-2-update-2-released.aspx). After this happened, once I edited the work item with the multi-value custom control (I didn't modify the control, just changed a label for a different field in the work item), the control re-sized to be too wide (126% in our case) for the work item in web access. This occurs during the _setButtonWidth function in the javascript. We cannot revert this sizing issue even if we redeploy the same work item definition that was used before. There is no sizing issue on our server that has not updated yet, which makes me suspect this is a small issue with the new update for TFS. We have noticed other bugs due to this update as well. How can I get this custom control resized to fit into the work item again? Thanks.
