Invoked state machine sends event but QScxmlStateMachine::connectToEvent cannot capture it

Reproducer attached. It features a parent state machine that will invoke a child state machine. The child state machine is going to send out an event on entering its only state.

Expected result:
"testevent received "testevent" QVariant(QString, "from invoked")" should be output to console since that should be capture by QScxmlStateMachine::connectToEvent set to the child state machine.

Actual result:
No such output. Although child state machine is working (one can tell from the other 2 logs), no event is captured.
