CSS Module Loader Order and Groups

[solmsted]

I've run into issues with loader loading CSS modules out of order. The issue is reproducible when one module is grouped and another module is not grouped. Here is an example:

http://jsbin.com/ahofis/1/edit
my-css requires other-css so I expect the <link> for other-css to appear first in the DOM, but it does not.

http://jsbin.com/ahofis/2/edit
Specifying that my-css should load after other-css does not work.

http://jsbin.com/ahofis/3/edit
http://jsbin.com/ahofis/4/edit
http://jsbin.com/ahofis/5/edit
It works correctly when both modules are ungrouped, when both modules belong to the same group, or when both modules belong to different groups.
