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)
Running the following script with and without the sleep command.
```
#!/bin/bash
git -c init.defaultBranch=master init
git config user.email "e@xxxxxxxx"
git config user.name "Name"
git commit -m init --allow-empty
git checkout -b otherBranch
git commit -a --allow-empty -m first
git checkout master
git merge --ff otherBranch
git notes add -m foo
# sleep 2
git reset --soft HEAD~1
git commit -a --allow-empty -m first
git notes add -f -m bar
git log --graph --abbrev-commit --decorate --all
git checkout otherBranch
git notes show
```
What did you expect to happen? (Expected behavior)
I expected that the sleep command will not affect the behavior of the script.
What happened instead? (Actual behavior)
Without the sleep command, the note attached to the HEAD of otherBranch contains the message "bar" (most of the time).
With the sleep command, the note attached to the HEAD of otherBranch contains the message "foo".
What's different between what you expected and what actually happened?
Without the sleep command, the last commit will have the same commit id as the HEAD before the reset.
Because of this collision, we can not attach notes to HEAD of the master and the HEAD of otherBranch independently.
Anything else you want to add:
I tested this on git 2.35.1, 2.30.2 and 2.21.0, and they are all affected.
I attached the console output of the script with and without the sleep command to this mail.
