Screen magnification does not auto-pan when fragment dialog pops up.

1. We auto pan when certain type of window pop up to make sure the user
   knows about the context change. This does not happen however for
   fragment dialog since its window type is not in the list of one
   we auto pan for. Updating the window type list.
