[skyper]

What steps will reproduce the problem?

1. Have two ways, one member of at least one relation
2. Select the way with membership and Ctrl+C
3. Select the other way and "Paste relation"

What is the expected result?

JOSM tries its best to find the proper position in the relation list

What happens instead?

New members are simply place at the bottom of the list

Please provide any additional information below. Attach a screenshot if possible.

See #19300 for a similar problem in core.
"Split way" already includes some mechanisms to find the proper position in member list.
