Anything else?

Ran into this issue after upgrading the NgRx repo to Angular V13 RC0 packages and trying to run tests.

Running tests with Jest fails with the jest-preset-angular package and Angular v13 RC0 due to defined exports in the package.json in the @angular/compiler-cli package.

Thanks for the report @brandonroberts - I think there will be a few 3rd party libraries out that there will be affected by the changes to the packaging format in v13. It is good to get this visibility now during our RC period.

This is effectively a duplicate of #43833 - so let's close this and focus our discussions there.
