Yes.  But Stefan now changed it back.

Therefore, I was talking only about the 2nd part of your report, which
complains that the fine diffs are incorrect.

Again, that part is now gone; Emacs behaves like before: it shows fine
diffs only in the current hnunk.

#1 is solved; do you agree that #2 is not a bug, but the intended
behavior that was always there?
