It seems that the justification settings for the last system are not taken into account when the final bar contains a multi-bar rest. Is it an expected behavior?
I have not found any information about this here or in the manual—sorry if I missed it.
In this file, I set up the last systems not to be justified under 60%, which perfectly works except when the last measure contains multi-bar rests.
(I know I can adjust this manually , but I was wondering if there was a global setting I had missed.)
