Incorrect repeat in MIDI export when section break is present

Issue type

UX/Interaction bug (incorrect behaviour)

Description with steps to reproduce

1. Take the attached score
2. Open in 4.7.5 (and latest main, but that has a different issue on top, see #34870)
3. Delete the bogus section break at the title frame (although it doesn't really harm)
4. Play, notice the playback works and pauses only before the next section, not at the repeats/jumps
5. Export to MIDI (expand repeats, of course)
6. Play the MIDI and notice that it doesn't pause at the section breaks at all
   EDIT: notice it pauses at every section break, repeat or not, so shows the very bug that got fixed for playback
