LongtapEvent happens only once per component

LongtapEvent happens only once per component. On longtap event I can see the 
following stacktrace in gwt dev mod console:

Code example:

package client;

public class LongTapModule implements EntryPoint {

    public void onModuleLoad() {

        GWT.setUncaughtExceptionHandler(new GWT.UncaughtExceptionHandler() {
            public void onUncaughtException(Throwable throwable) {
                throwable.printStackTrace();
            }
        });

        Scheduler.get().scheduleDeferred(new Scheduler.ScheduledCommand() {
            @Override
            public void execute() {
                locateTestPanel();
            }
        });

    }

    private void locateTestPanel(){
        TouchPanel touchPanel = new TouchPanel();
        touchPanel.getElement().setInnerText("Touch panel");
        touchPanel.addLongTapHandler(new LongTapHandler() {
            public void onLongTap(LongTapEvent event) {
                Window.alert("Long tap event");
            }
