[BUG] Angular app with formiojs not working on Mozilla, IE 11, Edge

[MihaiRebegea]

Environment

I have an Angular app where I integrated formiojs.
I'm not using the formio-angular component because I need to authenticate the user via token swap and I'm using formIOFetch plugin to fetch some data from my backend.

• Hosting type
  • Form.io
  • Local deployment
    • Version:
• Formio.js version: 4.9.26
• Frontend framework: Angular version 8
• Browser: Mozilla, Internet Explorer 11, Edge
• Browser version: Mozilla 76.0.1, IE 11, Edge 44.18362.449.0

Steps to Reproduce

1. Create simple Angular component
2. Import formiojs
3. Use anything related to formio in the component for ex: Formio.logout();

Expected behavior

App should start without issues like on Chrome or Opera

Observed behavior

Blank screen appears in Mozilla, IE11, Edge.

Following error appears in the console:

Error: "Zone.js has detected that ZoneAwarePromise (window|global).Promise has been overwritten.
Most likely cause is that a Promise polyfill has been loaded after Zone.js (Polyfilling Promise api is not necessary when zone.js is loaded. If you must load one, do so before loading zone.js.)"

I found this ticket which states the same error formio/angular-demo#15
However updating to formiojs version 4.9.26 didn't do the trick for me.

Thank you in advance for your help

I believe this was resolved with the latest version of angular-formio.

formio/angular#552
