nothing to commit, working tree clean

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-13.4 13.4
# Navigate to the new working tree
cd .worktrees/backport-13.4
# Create a new branch
git switch --create backport-1434-to-13.4
# Cherry-pick the merged commit of this pull request and resolve the conflicts
git cherry-pick 1b990e63dfab5400d902c0eba8b2255b37e34568,5259f30dc83cce4c38396e1eb556e6b388390910
# Push it to GitHub
git push --set-upstream origin backport-1434-to-13.4
# Go back to the original working tree
cd ../..
# Delete the working tree
git worktree remove .worktrees/backport-13.4

Then, create a pull request where the base branch is 13.4 and the compare/head branch is backport-1434-to-13.4.
