Weird interaction of paper variables, lyrics, rehearsal marks and span bars

[Kevin Barry]

Hi All,

The behaviour I am seeing is very strange. I have done my best to
reduce it to as little code as possible (which is why it looks a bit
strange), but I can't find anything more I can remove without making
the problem suddenly disappear. Please accept my apologies that this
is not a very minimal example. It requires a full page of music to
reproduce.

The problem is that the SpanBars in the last score have jumped out of
the score altogether into the space above it. If somebody could at
least confirm this behaviour on their system then I would be very
grateful to have ruled out my own setup, which is version 2.19.49 on
Fedora 24.

Thanks,
Kevin
