When using the OnClick event on a DropDownButtonItem, the MouseEventArgs parameter is always null. However, if the OnClick event is used on the main TelerikDropDownButton component, the MouseEventArgs works correctly.

After moving down to the desired DropDownButtonItem with the arrow key, the "enter" key will not trigger the OnClick event of the selected DropDownButtonItem.
