Webpack "magic comments" do not work in Worker constructors

[benjamind]

Bug description

Worker constructors don't work with magic comments so chunks cannot be easily named.

new Worker(
        /* webpackChunkName: "foo-worker" */ new URL(
            "../foo-worker.ts",
            import.meta.url
        ),
        { type: "module" }
    );

Filed a separate ticket on esbuild project where this needs to be fixed: evanw/esbuild#2439

Reproduction

Use the following syntax to load a worker with a webpack chunk name magic comment:

new Worker(
        /* webpackChunkName: "foo-worker" */ new URL(
            "../foo-worker.ts",
            import.meta.url
        ),
        { type: "module" }
    );

Note that the worker chunk does not have the name correctly applied.
