When the Chinese IME typing is used and the minLength is set in the ComboBox the items can not be properly selected using the keyboard.
When minLength is defined the item in the ComboBox is not selected, the dataitem is not accessible in the change event handler (screencast). The item is selected as expected if the value is copy pasted (包).
The items should be selected when using the Chinese IME typing after filtering the data and selecting an item through the keyboard.
