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-branch-8-6 branch-8-6
# Navigate to the new working tree
cd .worktrees/backport-branch-8-6
# Create a new branch
git switch --create backport-1086-to-branch-8-6
# Cherry-pick the merged commit of this pull request and resolve the conflicts
git cherry-pick 1f8f741b66c7aa45809d59d34e0ed9418a42cbd2,ed1b0b07210bf572c1124757d276d4a2ce342d76,5fbe773ec2861de7fb171f3a6ba4a2f5575bc3c0,45899da13e390896a2831267abd37bd375e9e03a,e91629068af7dd4046a01427441f3003fe18556d,b54e22d7c74949b4900a27908c82b122ecca71d2
# Push it to GitHub
git push --set-upstream origin backport-1086-to-branch-8-6
# Go back to the original working tree
cd ../..
# Delete the working tree
git worktree remove .worktrees/backport-branch-8-6

Then, create a pull request where the base branch is branch-8-6 and the compare/head branch is backport-1086-to-branch-8-6.
