Back button behaviour iOS

Hi everyone. I have noticed a bug on iOS. My app has four tabs, and navigation within each tab. In any tab, when I navigate to a sub page, then repeatedly tap on the back button, I can continually loop through the process of navigating back. The page continually reappears then navigates back. I understand this is not “real world” behaviour of course. Just wondering if anyone on the team is aware of this behaviour and if there is a fix for it.
