Hello,
After the change at 4c1a4b1, org-ql-completing-read always appends the outline path to the headline, even if org-ql-completing-read-reverse-paths is set to nil.
For example, if you have a headline at level 3 and org-ql-completing-read-reverse-paths is nil, the formatted candidate will be
Level 3 / Level 1 / Level 2
and if you have four levels, it will be
Level 4 / Level 1 / Level 2 / Level 3
The expected output here is
Level 1 / Level 2 / Level 3 / Level 4
and org-ql-completing-read behaved like this before.
