Safari iOS15 beta 8 address bar different behaviour in LM and PM

Hello there. I am facing an issue with Safari iOS 15 beta 8(noticed it on beta 7) on iPhone 8 Plus. In portrait mode I am able to reduce height of my webapp to 100vh without showing address bar. But in landscape mode I am unable to do that, height should be about 121vh to avoid showing address bar. Is that defect of Safari or is there any workaround?

I even uploaded video of the issue, to make it clear https://youtu.be/0FXiIUczLbQ

I am facing the same problem. Any updates on this one?
