-Make sourcemaps self-hosted
+Remove sourcemaps URL
 
-Normally source maps get removed as part of the build process so prevent that
-from happening.  Also avoid using the windows.net host since obviously we can
-not host our source maps there and want them to be self-hosted even if we could.
-
-To test try debugging/browsing the source of a build in a browser.
+These will not work since we patch VS Code.
