expose-loader works in Chrome but not FireFox?

Hi there!

After some issues with upgrading from 0.7.5 to 2.0.0 everything where fine with expose-loader thanks to @alexander-akait (Issue#129), until we tested in Firefox and we got several errors.

First off these ones works in both FF(Version 88) and Chrome(Version 89.0.4389.128):

import "expose-loader?exposes=React!react";
import "expose-loader?exposes=ReactDOM!react-dom";
import "expose-loader?exposes=moment!moment";
import "expose-loader?exposes=Tours!./tours.js";

Then we have several entrys like this:

   entry: {
    bla: ["./bla"],
    bla_app: ["./bla_app"],
    bla2: ["@babel/polyfill", "./bla2"], 
    bla3: ["./bla3"],
    bla4: ["./bla4"],
    bla_5: ["@babel/polyfill", "./SinglePage/bla_5.js"], 
    bla_6: ["@babel/polyfill", "./SinglePage/bla_6.js"],
    },

each entry has its own set of react components that we need to expose to our Razors views to be rendered: import "expose-loader?exposes=Components!./bla_index.js";

This works without problem in chrome, but fails in FF: Uncaught Error: [exposes-loader] The "Components" value exists in the global scope, it may not be safe to overwrite it, use the "override" option and every component from bla_index.js that should be renderd gets undefined. React.createElement: type is invalid -- expected a string (for built-in components) or a class/function (for composite components) but got: undefined. You likely forgot to export your component from the file it's defined in, or you might have mixed up default and named imports.

If I add this to webpack:

{
test: require.resolve("./App/bla_index.js"),
loader: "expose-loader",
options: {
	exposes: {
		    globalName: "Components",
		    override: true,
		},
	},
},

For every file that has its own set of components, this results in 5 of these. Then I can change the import to: import "./bla_index.js"; I can even leave it: import "expose-loader?exposes=Components!./bla_index.js";

Now both FF and Chrome works, if I take away the import completely both of them stop working.

What’s in play here? What is it I’m misunderstand?
