20605	Relation editor: Connectivity: Problem with dual-carriage, open end on top with only one way for one direction	skyper	team	"This is a follow-up of #19633, under special condition.

==== What steps will reproduce the problem?
1. Have a `route=road` relation with both ends split per direction and open ended and at least one of the direction branch consisting of only one way. See [attachment:ticket:6166:route_with_dual_carriage_on_several_end.osm.xz​ example file]
1. Sort the relation in relation manager
1. Look at the connectivity displayed on the start/end
1. Sort again (all members are flipped)
1. Look again at the start/end.

==== What is the expected result?
Complete connection displayed on all ends.

==== What happens instead?
Only on top and with at least only one direction branch consisting of only one way, connectivity is broken and ""jump to gap"" interprets it as gap. 
==== Please provide any additional information below. Attach a screenshot if possible.
