Track IME composition range updates as key.CompositionEvent and route them to the focused editor. Draw a thin underline under the current composition range using the editor text material. Keep the composition range in imeState so it is reset with the rest of the editor input method state, and normalize it in input.Router before forwarding CompositionEvent.
