I understand that Cursor::rewind(0) should reset the cursor to the beginning of the current score. However, it doesn't always do:

cursor.rewind(2);
cursor.rewind(0);

After these two commands cursor.segment will be null.
When there's no selection and staffIdx is reset to 0 before calling rewind(0), it works like expected.
I attached a demonstration plugin to check.

Looks like I didn't really understand how rewind(0) is supposed to work.
However, what happend here is, that cursor.staffIdx=0 does not reset the voice number, so cursor.track might still be 3 for example. If voice 4 of the first staff is empty, rewind(0) will not go to the start of the score.
Maybe it's worth mentioning in the documentation that setting cursor.track instead of cursor.staffIdx before calling rewind(0) is a good idea...
