Missing barline with a horizontal frame followed by start repeat
1) Insert a horizontal frame untile the page border, in order to flip the next bar to the staff below;
2) Insert a "start ritornello" barline at the first measure of the staff under the frame.
Problem: there's no barline at the end of the prevoius bar (before the horizontal frame).
If there's no riturnel in the second measure, the barline is visible.
The problem persist after previewing or printing.
I attach a mscz file and a screenshot.
