The backport to 4.0 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-4.0 4.0
# Navigate to the new working tree
cd .worktrees/backport-4.0
# Create a new branch
git switch --create backport-15348-to-4.0
# Cherry-pick the merged commit of this pull request and resolve the conflicts
git cherry-pick -x --mainline 1 deb7cf8ba5d7531b764350f16310f0a01d2899d2
# Push it to GitHub
git push --set-upstream origin backport-15348-to-4.0
# Go back to the original working tree
cd ../..
# Delete the working tree
git worktree remove .worktrees/backport-4.0

Then, create a pull request where the base branch is 4.0 and the compare/head branch is backport-15348-to-4.0.
