24741	Route GPX-export: close Route starting or ending with a roundabout	PPete2	team	"Identification: JOSM/1.5 (19555 de) Windows 11 64-Bit

There's a bug if exporting a route with ""Export GPX file starting from first member"" if the route start or ends with a (unsplitted) roundabout. In this case the track within the exported GPX file is not closed since it lacks the part of the roundabout.
Example which starts with a roundabout: https://www.openstreetmap.org/relation/19726489
