On selecting a panel bar item I am opening up a modal which in turn returns back a true or false.if true I am displaying the new item .if false I am staying on the previous item.but in case of false scenario even if I am staying at the previous item, as the next item was clicked ,the focused and selected property of that item is getting set to true and that of the previous item to false.how do I revert the selected and focused property if I don't display the itemcontent even if the user clicks on it.
