When submitting a build override the Expiration date field has a calendar icon, but surprisingly clicking it does nothing. Clicking in the textbox opens a date chooser widget.

I'm sure I can't be the only person who expects the calendar icon to open the date chooser widget. Currently the calendar icon serves no purpose, I know that 2015-08-27 is a date, and the title for the textbox also says "Expiration date" just in case I can't figure out what that textbox is meant to contain.
