There would be some timing difference (mainly from keyboard overlay transition) between 'focus' and 'resize' event. So 'resize' is the correctly event to go.
The process is: User app focuses the input field -> Keyboard app gets focus event via Keyboard API -> Keyboard app updates its url with hash -> Keyboard manager in System app is notified via mozbrowserlocationchange event -> Keyboard manager performs the opening transition of keyboard overlay -> In the end of the opening transition, keyboard manager notifies window manager with 'keyboardshow' event -> Window Manager in System app invokes 'current' app's |appWindow.resize()| method. -> appWindow calculates the height and adjust the size of the container, the iframe in the container is then resized -> Use app gets resize event.
