Resolved Unity WebGL build produces invalid code

Using Unity's WebGL build creates a blob file with invalid code in the very first line of code, here is the snippet.

Code (CSharp):

1. UnityLoader["7f320e7ff979e7e6fa1625bbb85f32db"]=
2. var UnityModule = (function() {
3.   var _scriptDir = typeof document !== 'undefined' && document.currentScript ? document.currentScript.src : undefined;
4.   return (
5. function(UnityModule) {
6.   UnityModule = UnityModule || {};

As you can see

UnityLoader["7f320e7ff979e7e6fa1625bbb85f32db"]=

has a dangling equals sign and the Javascript compiler throws an error of

Uncaught SyntaxError: Unexpected token 'var'

as a result.

This is blocking all progress on my game development. Is this something I can fix or is this a problem the Unity team needs to fix?

I am using angular 7 if that matters. I would like to exclude this file from the angular compiler but I cannot since, the filename is a random hash at the root directory with no extension.
