The backport to 1.6.latest 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-1.6.latest 1.6.latest
# Navigate to the new working tree
cd .worktrees/backport-1.6.latest
# Create a new branch
git switch --create backport-8527-to-1.6.latest
# Cherry-pick the merged commit of this pull request and resolve the conflicts
git cherry-pick -x --mainline 1 a0e13561b1e92e46559d68cbea469fb1923b8240
# Push it to GitHub
git push --set-upstream origin backport-8527-to-1.6.latest
# Go back to the original working tree
cd ../..
# Delete the working tree
git worktree remove .worktrees/backport-1.6.latest

Then, create a pull request where the base branch is 1.6.latest and the compare/head branch is backport-8527-to-1.6.latest.
