Top-level navigation to the shop origin. On the shop page: complete “payment”, then tap “Return to your world”. Watch whether the sheet dismisses itself when you return.
Opens the shop via window.open and tries to close it automatically 8 seconds later, from the game side. Just watch — touch nothing after tapping.
Same open, but you come back to the game yourself (dismiss the sheet with Done/✕), then tap “Close NOW” — checks whether a handle still works after the sheet was up.
