test: lock chunk filenames stay verbatim for scoped names (#21006)

alexander-akait · web-flow · commit 916810ebf619 · 2026-05-21T17:15:11.000+03:00
Regression test ensuring webpack does not URL-encode '@' (or other special characters) in entry names or webpackChunkName values. Mirrors the concern raised in jantimon/html-webpack-plugin#1771 against the plugin and pins the expected webpack-side behavior.
