Closes #8500

Can you add a test case to https://github.com/parcel-bundler/parcel/blob/v2/packages/core/integration-tests/test/vue.js for this example?

So duplicate https://github.com/parcel-bundler/parcel/tree/v2/packages/core/integration-tests/test/integration/vue-basic and make it fail with an error like in your screenshot, then add an assertion like this one

parcel/packages/core/integration-tests/test/javascript.js
