Unfortunately, I don't have time to repro this issue but I'm very sure ( and have just confirmed) when imports-loader and expose-loader are both applied on the same file, doing imports loader this=>window will not work since the imports-loader will try to 'call' the additionally wrapped function generated by expose-loader instead of the actual module function.
Solution
Remove expose-loader on the file and imports-loader will start to work
