PopupV2 - OnTappingOutsideOfPopup not called in OnBackButtonPressed

[tranb3r]

For a popup, OnBackButtonPressed does not invoke OnTappingOutsideOfPopup, even if OnBackButtonPressed checks GetCanBeDismissedByTappingOutsideOfPopup before closing the popup.
I think that both actions (tapping outside the popup and pressing back button) should behave the same, and should call OnTappingOutsideOfPopup.
So it's probably a bug. What do you think?

Yup - good catch - that's a feature we should implement. We should invoke OnTappingOutsideOfPopup in OnBackButtonPressed.
