File replacements are ignored for web workers
Command
build, serve
Is this a regression?
- Yes, this behavior used to work in the previous version
The previous version in which this bug was not present was
v18
Description
Hi, we recently updated to angular v19. During that we also migrated the builder to the recommended @angular/build builder, but in my tests the error also occured for the old devkit builder. After the update, we noticed that file replacements are ignored for web workers, see minimal reproduction. Before our upgrade, this was working without problems. I'm happy about any help :)
Minimal Reproduction
StackBlitz: https://stackblitz.com/edit/4gqtqodb
After everything was built, you will see in the console:
Component: production
Worker: development
However, as defined in the angular.json, the file env.ts should be replaced by env.prod.ts, which is done correctly in the component.

Anything else relevant?
Seems to happen for both build and serve, local and on stackblitz and for both the devkit and the new builder.
