Description

Found while testing #34106 cc @alan-agius4

Two entry points whose names differ only by / vs - (like zz/child and zz-child) get the same bundle name. The build passes with exit 0, one entry point's code overwrites the other's, and both exports point at the same file.

Minimal Reproduction
  1. projects/lib/zz/child/public-api.ts: export const NESTED = 'nested';
  2. projects/lib/zz-child/public-api.ts: export const FLAT = 'flat';
  3. entryPoints: "./zz-child": "projects/lib/zz-child/public-api.ts" and "./zz/child": "projects/lib/zz/child/public-api.ts"
  4. ng build mylib exits 0, fesm2022 has a single mylib-zz-child.mjs with only NESTED, and both ./zz-child and ./zz/child in exports point at it
  5. import { FLAT } from 'mylib/zz-child' fails in the consumer
