I get: 
VM730 stream_0.js:4097 Uncaught Error: Cannot find module 'function e(t,n,r){function s(o,u){if(!n[o]){if(!t[o]){var a=typeof require=="function"&&require;if(!u&&a)return a(o,!0);if(i)return i(o,!0);throw new Error("Cannot find module '"+o+"'")}var f=n[o]={exports:{}};t[o][0].call(f.exports,function(e){var n=t[o][1][e];return s(n?n:e)},f,f.exports,e,t,n,r)}return n[o].exports}var i=typeof require=="function"&&require;for(var o=0;o<r.length;o++)s(r[o]);return s}'

This is an error thrown directly by the code:
                var a = typeof require == "function" && require;
                if (!u && a)
                    return a(o, !0);
                if (i)
                    return i(o, !0);
                throw new Error("Cannot find module '" + o + "'")

I have no idea what this code is trying to do, there's a TON of obfuscated code here.

When I try in Firefox 54.0 I get the exact same error.

So I see no evidence that there's a browser bug here.  If you still believe there may be a browser bug here, please try to reduce the test case to something smaller and understandable.  See https://developers.google.com/web/feedback/file-a-bug.
