Broken handling of "J" hunks for "add --interactive"?

Thank you for filling out a Git bug report! Please answer the following questions to help us understand your issue.

What did you do before the bug happened? (Steps to reproduce your issue) git add --interactive

answer some "y", some "n", one "J"

What did you expect to happen? (Expected behavior) git will ask at end for exactly the one "J" hunk

What happened instead? (Actual behavior) git asked about the hunk rejected before the "J" hunk also (asked for two hunks instead of one)

What's different between what you expected and what actually happened? I did not observer that in an older version of git (like 2.26.2)

Anything else you want to add:
