Very cryptic and pointlessly aggressive report was created on https://github.com/streetcomplete/StreetComplete/issues/5243

I am now trying to figure out what is the problem, as reporter has not bothered to specify it.

It seems to be about splitting way belonging to relation https://www.openstreetmap.org/relation/1318928 and new way not being added to this relation, right?
 
If yes, then it is a bug as StreetComplete is supposed to do this
