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-v3.19 release-v3.19
# Navigate to the new working tree
cd .worktrees/backport-release-v3.19
# Create a new branch
git switch --create backport-3793-to-release-v3.19
# Cherry-pick the merged commit of this pull request and resolve the conflicts
git cherry-pick -x --mainline 1 3c7e1e68d07fc5080b1fc9bdb31124f48005daf2
# Push it to GitHub
git push --set-upstream origin backport-3793-to-release-v3.19
# Go back to the original working tree
cd ../..
# Delete the working tree
git worktree remove .worktrees/backport-release-v3.19

Then, create a pull request where the base branch is release-v3.19 and the compare/head branch is backport-3793-to-release-v3.19.
