Problem

How to reproduce

rm -rf dist/*
npm i
npm run build -- --project=test1 --prod
npm run build -- --project=test2 --prod
npm run build -- --project=test3 --prod
cd dist/test3
npm link
cd ../..
npm link @prebuilt/test3

npm run start -- --configuration=fromsource: does not work
npm run start -- --configuration=fromdist: works as expected

After that, fromsource builds will run too (because Ivy already did it's job), but I'm not sure if it would be linked correctly

How this project was set up

ng new code-splitting-repro
cd code-splitting-repro
npm run ng -- g library test1
npm run ng -- g library test2
npm run ng -- g library test3
