Should QHistoryState configuration be persistent between QStateMachine starts/stops?

Question

Let's say that my QStateMachine have a structure depicted below:

Note: actionsHistory is QHistoryState with initializeActions set as default state.

The transitions flow go like this:

1. actions
2. actionsHistory
3. initializeActions (default state for actionsHistory)
4. doActions
5. interrupt (after QEvent::User)
6. actions
7. actionsHistory
8. doActions (was an active state last time the actions were exited).

If I stop the machine and start it again, the transitions are different: machine never goes to initializeActions state, instead it jumps straight to doActions. It means that history of QHistoryState is not cleared on machine restart. Is it a correct behavior or a bug?

I've reported it as a bug, it should be fixed in Qt 4.6.3
