This has something to do with the \mark using
   Y-offset = ,side-position-interface::y-aligned-side
to get its initial Y-offset relative to the "Top"
After line-breaking, the marks are moved to the top-most visible staff,
and re-positioned relative to that.

The error went away when I made the tempo-spacing change, because I
changed the initial positioning of the \mark to be just above its parent
(Score or Top).   I think I'll revert that change so this bug will
reappear.
