\partCombine \pitchedTrill

[Pierre-Luc Gauthier]

Hi there,

In this MWE the trill pitch des''' is not displayed for some reason.

When \partCombineChords is forced, why doesn't both trill note get displayed ?

Side question :
Why isn't the second bar merged "chorded" by default?
Both parts seems \partCombineApart by default.

Thanks for your help
