Android Hardware Backbutton not working on Alert

When I have an Alert or an Action Sheet opened and press the hardware back button the navigation pops, if it can, otherwise the app closes and the Alert remains opened.
I would expect the Alert to close on hardware back button pressed and the navigation to remain on the same page as android users use the back button pretty often this really breaks the flow of the application.
Is this a known bug? Are there some workarounds or fixes?

What version of ionic-angular do you have in your package.json?
I just tried this with beta7 and everything is working as expected.

Beta6…maybe that’s the reason. Thank you for your answer
