On Android, when you interact with the on-canvas text tool input and summon an on-screen keyboard on Android, the entire application window will pan up if the initial position of the input is near the bottom of the screen. This is wrong, if the user wants to see the input, they can pan the canvas to bring it into view, they don't need their entire window shifted. It also puts the selection handles in the wrong place because Qt doesn't offset the transform correctly on its own. This probably requires patching Qt. QtNativeActivity.java has a variable m_softInputMode that decides on this behavior, but there's no interface for manipulating it.
