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-7.68.x 7.68.x
# Navigate to the new working tree
cd .worktrees/backport-7.68.x
# Create a new branch
git switch --create backport-20526-to-7.68.x
# Cherry-pick the merged commit of this pull request and resolve the conflicts
git cherry-pick -x --mainline 1 52ab2e0164ba65cdd7d4e8bdbdd77ac23da9afa8
# Push it to GitHub
git push --set-upstream origin backport-20526-to-7.68.x
# Go back to the original working tree
cd ../..
# Delete the working tree
git worktree remove .worktrees/backport-7.68.x
