How to reproduce the issue?

When adding a line with relations (e.g. separate multipoly away from some feature like footpath) I cannot merge the new line with another line containing same relations, when those relations are in different order.
This should normally work as the relation list contains same elements.

example: selected are 2 connected lines (sharing point on top-left):

line1 relations:

line2 relations:

Workaround: Edit the relations so they are in the same order then merge option is active and merge works.
Workaround2: Commit eventual changes (or restart editor) -> the merge option is available (also the relations are now in same order)

To reproduce (simple version): just split any line with 2+ relations, select one of the lines, delete first relation, add the same relation (will be added at the end). Merge the lines (will not work).

It's been like that for quite some time, and annoys the hell out of me; it was introduced with validation of relations on way merging. There's a set of related outstanding bugs - see also #8167, #9311.
