20644	Relation editor: Sorting of route relation never stops under certain conditions (gaps).	skyper	team	"This is a follow up of #19633 and #6166, see [/ticket/6166#comment:11 my comment 11].

==== What steps will reproduce the problem?
1. Have a completely mapped route relation with multiple gaps, see [attachment:ticket:6166:route_with_dual_carriage_on_several_end.osm.xz example file]
1. Open relation editor
1. Sort relation
1. Sort relation
1. Sort relation
1. ''and so one''

==== What is the expected result?
Sorting stops once there is no further improvement, which should be after the first full sort of all members

==== What happens instead?
Sorting never ends and all members all always flipped upside down.
 
==== Please provide any additional information below. Attach a screenshot if possible.
Maybe, this is a side effect of #20605, because the displayed connectivity is also wrong and non-existing gaps are displayed and jumped to.
