I probably mis-interpreted the code. Because then I would also fail for normal headings. Just thinking about the symptoms I think the issue Is that (org-end-of-subtree) works with type 'headline. And inlinetask is a different type, right?

IMO org-mode should consistently treat inlinetasks including the END line as a branch. Then org-cut-special would do something useful on them, i.e. cutting the inlinetask includinging its contents and the END line.

I looked directly into the code and I think I found the issue:
(org-copy-subtree) calls (org-end-of-subtree) without providing an element. But without an element this function just jumps to (point-max).
I would expect a different behavior or (org-end-of-subtree). Since element is optional it should take the element at point.

You may need to pull the latest main.

See https://orgmode.org/manual/Feedback.html#Feedback
REPRO_ARGS are just extra arguments passed to Emacs when opening it in a
clean environment in current Org git repo.
