I'm guessing you're using an Android device? On iOS and iPadOS, the
keyboard works more as an "overlay", like you want.

Unfortunately, on Android the keyboard works differently, and the
browser creates a resize-event. It's difficult to determine if that
resize was triggered by opening the keyboard or by something else.

For your specific case, the easiest solution might be to disable remote
resize and set the session size manually on the remote instead.

If that doesn't work for you, you can try to modify your code in this
function here:
