Extra "t-animation-container"s when opening and closing a comboBox rapidly

[John]

Hi,
 We have noticed that it is possible to open and close a combo box in our application quickly enough that there are a buildup of animation containers that persist until the page is reloaded. This has the side effect of preventing the comboBox popup from being displayed once any of these extra animation containers are present on the page, effectively rendering the comboBox inoperable. This problem cannot be reproduced on the Telerik example page.

The code for the combo box is: 

@(Html.Telerik().ComboBoxFor(model => model.Parent)
                           .Name("add-node-window-parent-node-id")
                            .AutoFill(true)
                            .DataBinding(binding => binding.Ajax()
                                .Select("SearchParentNodes", "Hierarchies", new { treeDate = @Model.TreeDate, hierarchyID = @Model.HierarchyID })
                                .Cache(false))
                            .Filterable(filtering =>
                            {
                                filtering.FilterMode(AutoCompleteFilterMode.StartsWith);
                            })
                            .HighlightFirstMatch(true)
                            .ClientEvents(events => events
                                .OnChange("addNodeParentNodeOnChange")
                                .OnDataBound("addNodeParentNodeOnDataBound")
                                .OnLoad("addNodeParentNodeOnLoad")
                                .OnOpen("addNodeParentNodeOnOpen"))
                        )

If anyone could provide any insight into this it would be appreciated.

Thanks,

-John

We updated our version of telerik and this is no longer an issue.
