18675	Join Areas: Tags and Membership from uninvolved objects copied	skyper	team	"==== What steps will reproduce the problem?
1. Have three closed ways, two of them overlapping and the third one with different tags or memberships than the other two. See attached [attachment:josm_join_areas_tag_bug_example.osm file].
1. Select all three ways
1. Join overlapping areas

==== What is the expected result?
The tags and memberships of the involved ways are merged to the (new) way

==== What happens instead?
All tags and memberships of all selected ways are merged to the (new) way, including tags and memberships of selected objects which were not joined as they do not overlap.

==== Please provide any additional information below. Attach a screenshot if possible.
Please, use only the tags and memberships of the involved objects and skip the other, thanks.
