If I attempt to show two transparent stages, initially only the last stage which I show is shown.
Once I close the last stage, the first stage is then shown.
But both stages should be shown at the same time.

Sample code:

import javafx.application.Application;
import javafx.scene.Scene;
import javafx.scene.control.Label;
import javafx.scene.layout.StackPane;
import javafx.stage.Stage;
import javafx.stage.StageStyle;

// should show (simultaneously) two transparent stages. Click on a stage to close it.
public class DualTransparentStagesBug extends Application {
    @Override
    public void start(Stage stage1) {
        StackPane layout = createLayout("1");
        stage1.initStyle(StageStyle.TRANSPARENT);
        stage1.setScene(new Scene(layout, 100, 100, null));
        stage1.getScene().setOnMouseClicked(e -> stage1.hide());
        stage1.setX(200);
        stage1.setY(200);
        stage1.show();

        Stage stage2 = new Stage();
        stage2.initStyle(StageStyle.TRANSPARENT);
        stage2.setScene(new Scene(createLayout("2"), 100, 100, null));
        stage2.getScene().setOnMouseClicked(e -> stage2.hide());
        stage2.setX(350);
        stage2.setY(200);
        stage2.show();
    }

    private StackPane createLayout(String text) {
        StackPane layout = new StackPane(new Label(text));
        layout.setStyle("-fx-background-color: rgba(255, 255, 255, 0.3); -fx-font-size: 60;");
        return layout;
    }

    public static void main(String[] args) {
        launch(args);
    }
}
