PaperSelect with selected=0

I have an array as selectOption=[0,1,2,3]

when the selected value is 0, it is not selected...

any idea why?
where

pageArray = [0,1,2,3]
page = 0,

{{pageNo}}

Start by reproducing the example with PaperSelect, options [0,1,2,3], and selected value 0, then inspect the component's selected-value handling. Done means 0 is visibly selected and the onChange action continues to update the selection correctly.
