Description
Which @angular/* package(s) are the source of the bug?
Don't known / other
Is this a regression?
No
Description
I came across this error and the fix seemed to be to remove the export const statement from the spec, then export it from its own file.
I first reported this to Vitest, but they pointed out that running the test using npm run test fails while simple running with the command vitest passes. The maintainers suggested that it was an Angular bug.
I created a new StackBlitz from the Angular template, ensured that it was the latest version of Angular, installed vitest and jsdom, and added the minimum config to get it up and running.
Please provide a link to a minimal reproduction of the bug
