Describe the bug

Source maps for the blockly-webpack sample don't appear to be working properly. Here are the errors that I'm seeing:

12:33:31.886 DevTools failed to load source map: Could not load content for webpack:///node_modules/blockly/blockly_compressed.js.map: HTTP error: status code 404, net::ERR_UNKNOWN_URL_SCHEME
12:33:31.886 DevTools failed to load source map: Could not load content for webpack:///node_modules/blockly/blocks_compressed.js.map: HTTP error: status code 404, net::ERR_UNKNOWN_URL_SCHEME
12:33:31.887 DevTools failed to load source map: Could not load content for webpack:///node_modules/blockly/javascript_compressed.js.map: HTTP error: status code 404, net::ERR_UNKNOWN_URL_SCHEME

Note that I'm using the blockly-webpack sample by running 'npm start' and going to localhost:3000 in my Chrome browser

To Reproduce

Steps to reproduce the behavior:

1. Fork/clone/download blockly-webpack sample
2. npm start
3. Go to localhost:3000 in Chrome browser
4. See above errors in Chrome console
5. Open source panel in Chrome debugger
6. Try to view any Blockly source file

Expected behavior

I expect to not see the errors shown above and to be able to view and debug Blockly source files.
