mapPartIntersectionso the loop stops beforeoldParts.lengthinstead of reading one past the end. It also adds a focused regression test that fails if the helper tries to accessoldParts[oldParts.length].Verification:
npm run lint:quiet -- src/utils/level-helper.ts tests/unit/controller/level-helper.tsnpm run type-check./node_modules/.bin/karma start karma.conf.js --client.mocha.grep='mapPartIntersection'
