headers for dev-server not working anymore after upgrade from angular 16 to 17 #27464
Description
Which @angular/* package(s) are the source of the bug?
Don't known / other
Is this a regression?
Yes
Description
I've created a new angular 17 app with ng new angular-tour-of-heroes.
After adding custom headers in angular.json:
"serve" {
"builder": "@angular-devkit/build-angular:dev-server",
"options": {
"headers": {
"Cross-Origin-Opener-Policy": "same-origin",
"Cross-Origin-Embedder-Policy": "require-corp"
}
}
}they are not present in the initial localhost (index.html) request. All subsequent requests contains the headers.
When creating a new angular 16 app and adding the same config it works for the initial request as well.
Please provide a link to a minimal reproduction of the bug

Please provide the exception or error you saw
In the real code we see the error `Uncaught ReferenceError: SharedArrayBuffer is not defined` due to the missing headers.
