Content Access Web Browsing Cannot Be Focused Programmatically

Trying to make requestFocus () in a WebView does not work until the user clicks on the control.

I know this should be possible, since htmlEditor can be focused this way (and I suspect it is based on a content WebView).

I am coding my own custom htmlEditor using a webview with "contenteditable" and I would really like to focus it, how can I do with a standard htmlEditor.

I believe this should be a problem with Javafx, and I have already passed it to Jira, but I am wondering if anyone can think of this for this.

UPDATE : jira issue number: RT-21695

Short Demo Code:

/* Demo webview */

public class WebViewConteneditableDemo extends Application {


String initialEditview = "<html><head>"
        + "</head><body contenteditable='true'>"
        +"</body></html>";

/**
 * @param args the command line arguments
 */
public static void main(String[] args) {
    launch(args);
}

@Override
public void start(Stage primaryStage) {
    primaryStage.setTitle("Webview focus demo");


    final WebView editor = new WebView();

    Button btn = new Button();
    btn.setText("Test Webview focus");
    btn.setOnAction(new EventHandler<ActionEvent>() {

        @Override
        public void handle(ActionEvent event) {
           editor.requestFocus();
        }
    });

    BorderPane root = new BorderPane();
    root.setTop(btn);

    root.setCenter(editor);
    editor.getEngine().loadContent(initialEditview);

    primaryStage.setScene(new Scene(root, 500, 450));
    primaryStage.show();
}
