Webpack dev server is bootstrapping twice for an unknown reason. (Note that only the dev-server has this problem, if I bundle the files, everything runs ok).
I'm seeing this line executing twice:
// Load entry module and return exports
return hotCreateRequire(790)(__webpack_require__.s = 790);
I can also see this line two times in my browser log:
[HMR] Waiting for update signal from WDS...
These are the used versions
"webpack": "^2.1.0-beta.21"
"webpack-dev-server": "^2.1.0-beta.4",
