8va alta dashed line freezing in smooth pan

Issue type

UI bug

Bug description

If a score has a 8va alta annotation, it will scroll smoothly along while playing, but as soon as it hits the left screen border, the dashed line "freezes" in place. This happens for zoom values ≤ 215%.

Steps to reproduce

1. Create a score that's wider than your screen in sub-215%-zoom, so that it can hit the left screen border in smooth pan playback.
2. Add a 8va alta annotation.
3. Playback in "Continuous view (horizontal)" with "Smooth panning" (from Preferences > Advanced) enabled in a zoom of 215% or less.
4. Once the line start hits left screen border, the dashed line no longer scrolls but stays fixed on screen (its end just gets shortened from the right up to the end hook).

Screenshots/Screen recordings

Illustration; you can see it's not just an optical illusion, because the line visually moves at first and only later appears to freeze.
I also included a "rall" for two reasons: firstly, to show that not every dashed line is affected. Secondly, it alters playback speed continuously so the amout scrolled per time constantly changes (if it were some kind of same-distance-pan optical illusion).
