Hi, https://gitlab.com/lilypond/lilypond/-/merge_requests/2256 attempts to solve https://gitlab.com/lilypond/lilypond/-/issues/3176 by introducing AgogicMark, AgogicSpanner and AgogicLineSpanner at score-level. It all mimics how DynamicLineSpanner collects and aligns dynamic stuff. So far all works fine. Alas, as soon as the relevant engravers are moved to another context, which is a common use case, I get an error:
programming error: cyclic dependency: calculation-in-progress encountered for AgogicLineSpanner.vertical-skylines and the graphical output is wrong. Again, this does not happen at score-level. Example-code to trigger it at #2256 I've no clue how to proceed. Every hint is very welcome. Thanks, Harm
