Note anchored lines duplicate when crossing pages

I thought I could use these as a workaround to the cross-page glissando behavior but it turns out they have their own artifacts as well.
If a note anchored line connects a note on page 1 and a note on page 2, then the half of the line that appears on page 2 will be mirrored to the same position on page 1. You can't do anything to the floating segment that doesn't affect the actual line. It's only visible on page view but will appear on exports from any view.
