791 follow-up: add test cases for relative reference where source is parent of target in a repeat #802
Description
As described here. So the source path is /a/s and target /a/s/t where the source is a non-repeating group label and the target is a text question. The comment says this was broken at (or before?) 4.1.0 then fixed by #791 (it was probably classified as a parent/child and so not processed properly before that) but anyway some test cases for this pattern are needed to ensure it stays fixed.
