Bug identified for history states when using self-transitions

[Bab64]

var sm = new scion.Statechart({
states: [
{
id: 'A',
transitions: [
{
event: 't2',
target: ‘A’ // Using 'History' here has same effect...
}
],
states: [
{
id: 'History',
$type: 'history',
isDeep: true,
transitions: [
{
target: 'A1'
}
]
},
{
id: 'A1',
transitions: [
{
event: 't1',
target: 'A22'
}
]
},
{
id: 'A2',
states: [
{
id: 'A21'
},
{
id: 'A22'
}
]
}
]
}
]
});

sm.start();
alert('Current: ' + sm.getConfiguration()[0]); // A1
sm.gen('t1');
alert('Current: ' + sm.getConfiguration()[0]); // A22
sm.gen('t2'); // Self-transition
alert('Current: ' + sm.getConfiguration()[0]); // A22 expected but A1 is displayed, why?
