What is the current behavior?

The this value of a config function passed to the module function is currently either window or undefined depending on your use strict state.

beforeEach(module('myApp', function($compileProvider) {
  // `window` or `undefined`
  console.log(this);
}));

What is the expected behavior?

Can we provide the this value from beforeEach so that this is the current spec in any config functions?

What is the motivation / use case for changing the behavior?

Ease of testability when using this to share content that should be spec specific

Sounds reasonable (assuming there aren't negative implications - I couldn't think of anything).
