Question re: the Cutaway feature

I don't know if this is the expected visual or not, but in the attached (Prokofiev's War and Peace, Andrei's Act 1 aria) I used the Staff Properties cutaway feature to mimic the original score's use of a Violin I divisi (measure 17), a solo Contrabass line (measure 28), and a Clarinet divisi (measure 55).
In all three places, the cutaway's first measure has no bar line visible at the section's beginning, but the last measure of the cutaway has the same bar line type as the rest of the score.
Maybe this is the desired property, but to me the missing bar line looks improper. Any thoughts?
