So, the problem is that when i try to ship my app as a standalone pwa app, after clicking on an in put and closing the keyboard, double tapping anywhere on the screen causes the screen to move up exacly as much as the height of the keyboard and display what i assume to be the body of my html! there is a similar issue on stackoverflow: https://stackoverflow.com/questions/55120331/white-panel-arrives-on-double-tap-from-bottom-in-pwa-in-standalone-mode
which has provided a good example actually:

How is one to solve such a vague issue is beyond me. Any Ideas?
