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-release/3.9 release/3.9
# Navigate to the new working tree
cd .worktrees/backport-release/3.9
# Create a new branch
git switch --create backport-10159-to-release/3.9
# Cherry-pick the merged commit of this pull request and resolve the conflicts
git cherry-pick 2bda0b9659e6c3c2d266a9eed0dc637c38cdc58e,26c163d1938ad4a7ea5de43eea0fa9e4d6ffc7bd,5ecffdf697be4882b39877cf4dd2a0cb91411812,e509d3438e053ffc7c537a95e89d517013348541
# Push it to GitHub
git push --set-upstream origin backport-10159-to-release/3.9
# Go back to the original working tree
cd ../..
# Delete the working tree
git worktree remove .worktrees/backport-release/3.9

Then, create a pull request where the base branch is release/3.9 and the compare/head branch is backport-10159-to-release/3.9.
