This issue happenned when using RadListBox with attached buttons.
Problem:
Click any one item in a RadListBox, and then click the item again.
All attached buttons of the RadListBox are disabled.
And the buttons can still work as expected when you click them.
Expected result:
Do not disable the button when it is able to be clicked.
