I'm using webpack to compile my application source. It splits up the files in chunks which are lazily loaded when necessary. However, the sourcemaps for the first file (main.js) breaks if the second file (2.js) is loaded in. 

Here's when it _does_ work.
- if I throw an error in main.js immediately instead of with a timeout
- if 2.js is not lazily-loaded but available in a script tag when the page is rendered

Here's what I've tried to make it work
- remove the sourcemap for 2.js
- remove the content of 2.js

They work in IE11 (with pause on exceptions enabled).

Not sure where to start. Is there any way I can get debugging information for source maps?
