How minChunks in CommonsChunkPlugin affect the custom css style rendering?

React CSS style is rendering later than custom CSS style, which is somehow dependent on minChunks.

new webpack.optimize.CommonsChunkPlugin({
    name: "common",
    minChunks: function(module, count) {
        return !couldThisGoToCommonBundle(module) && count >= 5;
    }
}),

new webpack.optimize.CommonsChunkPlugin({
    name: 'vendor',
    chunks: Object.keys(entryPoints).concat('common'),
    minChunks: function(module, count) {
        return couldThisGoToCommonBundle(module) && count >= 10;
    }
})

When I change the count >= 5 in vendor, the custom style is not distorted.
