QGamepadKeyNavigation have a bug on handling of ButtonL2/ButtonR2

    //Trigger buttons are a special case as they get multiple press events as the value changes
    if (button == QGamepadManager::ButtonL2 && buttonL2Pressed)
        return;
    else
        buttonL2Pressed = true;
    if (button == QGamepadManager::ButtonR2 && buttonR2Pressed)
        return;
    else
        buttonR2Pressed = true;

    if (button == QGamepadManager::ButtonL2) {
        if (buttonL2Pressed)
            return;
        else
            buttonL2Pressed = true;
    }
    if (button == QGamepadManager::ButtonR2) {
        if (buttonR2Pressed)
            return;
        else
            buttonR2Pressed = true;
    }
