Dropdown Datagrid virtualization causes popup refresh issues

Dropdown datagrid popup data refresh inconsistently with allowvirtualization=true. By adding below dropdowndown grid in cascade dropdown demo the issue is demonstrated

    <RadzenDropDownDataGrid AllowClear="true" TValue="int" AllowVirtualization="true" Data=@orders  TextProperty="OrderDate" ValueProperty="OrderID" Name="DropDownDataGridTextValueProperties" />

I also observed that the issue occurs the second or third time the data is filled. And once the data is empty the issue returns after second or third data refresh.

Issue confirmed! Fix will be released in our next update.
