Production build should not reference sourcemaps

Describe the issue

The production builds reference sourcemaps due to trailing comments.

bootstrap.bundle.min.js:

//# sourceMappingURL=bootstrap.bundle.min.js.map

bootstrap.min.css:

/*# sourceMappingURL=bootstrap.min.css.map */

That unfortunately spams the devtools console on every page load. Example from my dev machine::

Source map error: Error: request failed with status 404
Resource URL: http://localhost:80/bootstrap.min.css
Source Map URL: bootstrap.min.css.map

The production build should not have source map support, because it's unnecessary, it spams the console and generates significantly more traffic. (CDN-served assets also have sourcemaps in production builds.)

Reduced test cases

• Reference minified css and js files, either from local sources or CDN
• Open devtools console - errors
• Measure traffic - much more traffic as those map files are huge

Totally agree with this, I have to open up connect-src on the security policy for the whole of the CDN just because of this source map inclusion in a production build. It should at least be available without it as an option at a minimum.
