    Description

      After a QHistory state in mode "DeepHistory", signals entered/exit and functions onEntry/onExit are not called for all states on the path from HistoryState to the previous saved state.

      Here an example :

      QState* s1 = new QState();
      QState* sPause = new QState();
      
      m_stateMachine->addState(s1);
      m_stateMachine->addState(sPause);
      
      
      QState* s11 = new QState(s1);
      QState* s111 = new QState(s11);
      QState* s112 = new QState(s11);
      s11->setInitialState(s111);
      s111->addTransition(s112);
      
      
      QHistoryState* l_hist = new QHistoryState(QHistoryState::HistoryType::DeepHistory, s1);
      l_hist->setDefaultState(s11);
      
      s1->setInitialState(s11);
      
      m_stateMachine->setInitialState(s1);
      
      s11->addTransition(this, SIGNAL(togglePause()), sPause);
      
      sPause->addTransition(this, SIGNAL(toggleResume()), l_hist);
      

      Enter s1
      ___Enter s11
      ______Enter s111
      ______Exit s111
      ______Enter s112
      toggle Pause
      ______Exit s112
      ___Exit s11
      Exit s1
      Enter sPause
      toggle Resume
      Exit sPause
      Enter s1
      ___Enter s11 Missing
      ______Enter s112
      toggle Pause
      ______Exit s112
      ___Exit s11 Missing
      Exit s1
      Enter sPause
