`npm ci` does not fail when package is incorrectly marked as dev

What I Wanted to Do

Move a package from devDependencies to dependencies, then run npm ci --only=production and get an error

What Happened Instead

npm ci --only-production passed and removed the package.

Reproduction Steps

git clone
cd npm-ci-issue
npm run test
