Description

The problem with ios keyboard and webapp exist since webapp exists
When a input exist under the keyboard telegram tries to show it but it shows half of the input also sometimes even with disabled overflow on webapp a weird scrollbar appear and you can basically scroll webapp or sometimes even gesture is not working and you should close the webapp and open it again
Android version handle this very perfectly so I upload both ios and android with same environment to see difference between these two platform

First when I came across with this issue I just add some bottom margin to input and make it top of the screen but this won't work in every situation like limited height and etc

Expected Behavior

What I want you to do is disable that weird scrollbar if webapp owner want scrollbar he allow overflow and also when the keyboard opens bounce the whole webapp up to input be visible so user have better UX
