Is this a chore or a fix? 🤔 Also should we backport this?

[quinna-h]

@erikayasuda Thank you for the callout! I just added a releasenote, and backport labels :)

The backport to 2.13 failed:

The process '/usr/bin/git' failed with exit code 1

To backport manually, run these commands in your terminal:

# Fetch latest updates from GitHub
git fetch
# Create a new working tree
git worktree add .worktrees/backport-2.13 2.13
# Navigate to the new working tree
cd .worktrees/backport-2.13
# Create a new branch
git switch --create backport-11145-to-2.13
# Cherry-pick the merged commit of this pull request and resolve the conflicts
git cherry-pick -x --mainline 1 f3b5275b8a6be8d3b7c8ab1e4e40ed96cb9aa386
# Push it to GitHub
git push --set-upstream origin backport-11145-to-2.13
# Go back to the original working tree
cd ../..
# Delete the working tree
git worktree remove .worktrees/backport-2.13

Then, create a pull request where the base branch is 2.13 and the compare/head branch is backport-11145-to-2.13.
