I may have found a bug where a finger glide line does not connect to a finger number on one side when said finger number collides with and is placed above a tuplet number.
\version "2.24.2" \relative c'' { \stemUp \override Staff.Fingering.outside-staff-priority = #1 \tuplet 3/2 { c8 c\glide-1 c-1 } } I checked the internals manual, but I did not see a property that I could adjust to work around this issue. If this is not a bug and/or there is a way to get desired behavior, then please tell me what I can change for lilypond to produce desired output.
