Horizontal frame before last measure of system creates crowded layout
GIT commit: 42bdb5f
1) load attached file
2) insert horizontal frame before last measure of system
3) enlarge frame
Result: the last measure should be pushed to the next system long before it is.
This seems to be a special case of the issues in #24100: Horizontal frame at end of system followed by staff names, most of which were fixed, but somehow this particular case still doesn't work correctly.
