Rsbuild use SWC to minify the JS code, and SWC does not supports keep_fnames RegExp yet, see:

• https://swc.rs/docs/configuration/minification#jscminifymangle
• https://github.com/search?q=repo%3Aswc-project%2Fswc+keep_fnames&type=code

You can submit an issue to the SWC repo to request this feature 😄

Also, we plan to support using Terser as the JS minimizer in Rsbuild / Rspack projects, ref: web-infra-dev/rspack#3639
