[Drawer] not working when using ignore-styles

[Itagiba]

Problem description

Hello, I am currently using ignore-styles to prevent babel-register from interpreting my sass files as .js, It solves the problem. However it seems to break some of the material-ui components.

On the browser console, it shows the following error:

ignore-styles.js:45 Uncaught TypeError: Cannot read property '.css' of undefined

And the drawer menu stops working.

This is what it is pointing to in ignore-styles.js (45):

    oldHandlers[ext] = (void 0)[ext];
    (void 0)[ext] = handler;
  }

What does this mean exactly? Is this a known bug?

Getting similar error: TypeError: Cannot read property '.js' of undefined
I'm not using ignore-styles, but maybe can be related to material-ui? I'm not sure.

After building with webpack (v1.13.1),

Error thrown here: oldHandlers[ext] = (void 0)[ext]; in hookExtensions()

The error seems unrelated to Material-UI. I'm closing it.
