Keyboard on mobile doesn't push up the content #170
Description
Hello, and thank you for the library!
While implementing a chat interface I noticed a weird behaviour - when on mobile (Android, not sure about iOS) and you click to type (click the MessageInput component) the keyboard hides half of the screen. If you start typing then it pushes the content up, and focuses on the input field. In my opinion this behaviour should happen on the initial click, not after you start typing. This can also be observed on the demo chats.
Any ideas how this can be solved?
