Debugging bundled react library in bundled react app

I try to write a react library and test the components with an app. In my workspace in VS Code there is the ./lib directory and ./app directory.

Lib gets bundled by Rollup, gets type definitions via tsc and built via rollup-plugin-esbuild-transformer. A sourcemap gets created in Edge i can access the files of lib in the DevTools.

App was created via create-react-app, so webpack is responsible for all the bundling. I also linked Lib via yarn link lib.

Now when i try to set a breakpoint in an App-file everythings okay. Not so when trying to place a breakpoint in a lib-file like config.ts, this one gets ignored when placed in VS Code. When placed in Edge or by stepping down into the library functions VS Code opens a config.ts, but not the original one.

Lib: Rollup.json:

import styles from 'rollup-plugin-styles';
import esbuild from 'rollup-plugin-esbuild-transform';
import packageJson from './package.json';
const config =
{
    input: './src/index.ts',
    output: [
        {
            file: packageJson.module,
            format: 'esm',
            name: 'selftest',
            sourcemap: true,
        },
    ],
    plugins: [
        styles(),
        esbuild([
            {
                loader: 'json',
                minifyWhitespace: true
            },
            {
                loader: 'ts'
            },
            {
                loader: 'tsx',
                banner: "import * as React from 'react'",
                sourcemap: "both",
                sourceRoot: "../../selftest/src/"
            },
            {
                loader: 'js',
                include: /\.[jt]sx?$/,
                target: 'es2017',
                sourcemap: "both"
            }
        ])
    ],
    external: [
        'react-dom',
    ],
}
export default config;
