Current behavior
Currently, if auto is set to true for the file upload opens the choose window only once. Clicking it a second time has no effect.

Expected behavior
Die choose file dialog opens and another file can be selected.

Minimal reproduction of the problem with instructions
This issue can be reproduced on the PrimeReact samples page. Maybe this behavior is intetnional. But if possible, it would be easier to deal with the component if you could open the choose dialog multiple times.
