Ties on series of tied notes on center line flipping direction (randomly?)

[Richard Shann]

Hi,

Has anyone experienced the direction of ties on a series of tied notes
on the center line of the staff flipping direction, seemingly at
random?

I attach an example, but I haven't been able to cut the file concerned
down while keeping the effect - if I delete the lyrics for example the
problem at that point goes away and if I delete bars likewise (*).

I guess this might be related to the question of how LilyPond decides
the direction for ties on notes on the center line in any case? I am on
version 2.22 of LilyPond.

(*) I should add that as my lyrics are written separately from the
notes, deleting bars without deleting the corresponding lyrics as I did
does alter the underlay of the lyrics, so perhaps it is all lyrics
related...
