I am not able to reproduce the issue same as in the video : https://github.com/andy-goryachev-oracle/Test/issues/6#issuecomment-3726867016
I am using chinese input (Pinyin - Simplified) and typing some text in RTA and click enter or a number (1-2-3-...) have the same result as in a TextField
I could be missing something in the steps to reproduce.
Tried it in MonkeyTester and a simple app with both RTA and TextField  : 

    @Override
    public void start(Stage stage) {
        TextField textField = new TextField();
        textField.setPromptText("TextField");
        RichTextArea richTextArea = new RichTextArea();
        richTextArea.setPrefHeight(200);
        VBox root = new VBox(10, textField, richTextArea);
        stage.setScene(new Scene(root, 400, 300));
        stage.setTitle("TextField + RichTextArea");
        stage.show();
    }
