Continuous view misplaces auto-placed 8va alta annotations

Issue type

Engraving bug

Bug description

In Page mode or Continous vertical mode, the score looks fine. But in continuous horizontal mode, the 8va alta annotations are misplaced and overlap with the score.

Steps to reproduce

1. Create a score that starts in the staves, goes above it and back down, use engraving that goes even beyond, add 8va alta in auto-placement mode.
2. The placement is fine in page view.
3. Switch to continuous view.
4. The 8va alta annotation now overlaps with the score.

Additional context

I understand this is a trickier problem as it seems, because the 8va alta annotation might span multiple systems in page view with different offsets. I suppose the biggest (by absolute value) offset must win.
