cursor.addNote doesn't update internal segment reference

Triggered by the report in https://musescore.org/en/node/97556 we discovered that Cursor.addNote() already moves the internal input position of the score to the next segment BUT it seems to not (correctly) update the internal segment reference of the Cursor itself.

Creating a score in 4/4 and adding 6 1/8ths using cursor.addNote results in 6 subsequent notes (as expected), but leaves cursor.segment/measure/tick as it was (tick remains at 0).
Alternatively, calling cursor.next inbetween each addNote call (as is done in the exemplary random2.qml plugin) results in unexpected rests inbetween the added notes:

During creation the following was logged:

The defect seems related to the code having to 'reinstate', whatever that may be.
I think it might be as simple to fix as updating the _segment of Cursor at the end of addNote.
