Is this a regression?

Yes, the previous version in which this bug was not present was: 9.0.0-next.8

Description

The assets are not served in e2e tests, leading to errors in the console and failing e2e task.

🔬 Minimal Reproduction

This is fairly straightforward to repro:

npx @angular/cli@9.0.0-next.9 new e2e-assets --defaults
# update app.component.html to add something from src/assets like an image
ng e2e

I put together a small repro: https://github.com/cexbrayat/e2e-assets

Anything else relevant?

Reverting to 9.0.0-next.8 removes the error.

I realize there is also an issue when running ng build --prod, but it’s maybe the same. In my repro, I have an image in src/assets. If the image is in src/assets/images, then running ng build --prod throws: Unable to copy assets: ENOTSUP: operation not supported on socket, copyfile '/Users/.../e2e-assets/src/assets/images' -> '/Users/.../e2e-assets/dist/e2e-assets/assets/images'.
