Impossible to create a double/dotted/dashed/final barline at the right end of a mutli-measure rest bar
1) Create a multimeasure rest bar.
2) Try to change the right side barline style to a double, dotted, dashed or final barline.
3) Notice that the barline remains unchanged.
This occurs on a score as well as in parts. Repeat barline styles seem to work normally.
