Use Web API beforeunload event to trigger the confirm dialog

Isn't this already implemented? If you are alive and try to exit the game, there will be a popup.

No. This issue is about opening a dialog when the window / tab gets closed (beforeunload event)

This was added in #1411, but it was always enabled so it was removed in #1704. IMO, this should be reintroduced, but only during gameplay.

Yeah i removed it because it interfered with the pattern purchase flow

I would like to take it if possible (@evanpelle don't know if mention is necessary but just in case ¯\(ツ)/¯)
