Code splitting issue with 0.11.5

Following #1088 (closed), 0.11.5 worked for our code-base, everything is loading correctly except dynamic import (code splitting)

Code like:

       case 'markup-templating':
            return import('prismjs/components/prism-markup-templating.min.js');
        case 'dns-zone-file':
            return import('prismjs/components/prism-dns-zone-file.min.js');
        case 't4-templating':
            return import('prismjs/components/prism-t4-templating.min.js');
        case 'markup':
            return import('prismjs/components/prism-markup.min.js');
        case 'docker':
            return import('prismjs/components/prism-docker.min.js');

is compiled to:

and fails during import with:

Uncaught (in promise) ReferenceError: require is not defined

the configuration looks like:

    const options: esbuild.BuildOptions = {
        entryPoints: {
            public: path.join(packagesDir, 'app-web/src/index.public.ts'),
            app: path.join(packagesDir, 'app-web/src/index.ts'),
        },
        metafile: true,
        outdir: webOutputDir,
        platform: 'browser',
        target: BROWSER_TARGET,
        splitting: true,
        format: 'esm',
        resolveExtensions: WEB_EXTS,
        external: [],
        loader: LOADERS,
        assetNames: 'assets/[name]-[hash]',
        chunkNames: 'chunks/[name]-[hash]',
        entryNames: isDEV ? '[name]' : '[name]-[hash]',
        ...esbuildOptions,
    };

I'm still investigating the root cause and I'll post updates with my findings.
