Double barline doesn't appear on the staff of the added instrument
Win 10 Pro
see the attached file:
I created a new score, with a treble clef.
I changed the bar line in bar 4 to a double bar line
I added a new instrument (Violincello)
The new instrument does not have the double bar line in bar 4
It should inherit all the bar lines from the existing staves, right?
This has been a bug since at least mid-may...
