With this PR all text input is delivered as committed text in an InputMethodEvent. JavaFX never receives  a KEY_TYPED KeyEvent. This simplifies things but will cause all manner of follow-on problems. We need a better solution.

I cannot easily run Linux Mint since it doesn't provide an ARM version. This bug does not reproduce for me in a stock Ubuntu 24.04.3 environment which defaults to IBus. Does Linux Mint default to a different input method framework such as fcitx?
