bug: Unable to close modal/alert/bottomsheet on back or forth navigation ionic 4 (PWA)

[AkshayKanchan]

Bug Report

Ionic version:

[x] 4.6.2

Current behavior:
In browser (Mobile & Desktop) when a modal/Alert/BottomSheet is open and user navigates back using back button on browser, the modal stays open and background page is navigated anyway. There's no official way to handle the back button event programatically.

Expected behavior:
Any kind of overlays/Modals should be closed on back navigation.

Steps to reproduce:
Open a Modal/Alert/bottomSheet and navigated back or forth from browser using browser buttons (Navigation url should be of same Application) .

Thanks for the issue. I am going to close this as a duplicate of #15422. Feel free to follow that thread for any updates.

I guess its a bug not a feature request. Modal should be closed on back navigation instead of just navigating background page.
