withCredentials Kerberos - Preview and User Info not working

We are testing the kerberos authentication through ADF. We have taken the latest alfresco-js-api from develop which has changes related to "withCredentials". We have hard coded that value to "true" in local and build the content app pointing to the latest alfresco-js-api.

Authentication looks working fine but found couple of issues

1. Document preview doesn't work as document preview delegates http call to pdfJs library which does not consider the "withCredentials" setting. So authentication is failing for CORS requests.

2. The current logged in user name and the icon on the tool bar top right corner is not getting displayed. When we upload the content it identifies the user but not getting displayed on the UI toolbar.
   Expected behavior:
   The above two issues should be working as expected even with Kerberos

Steps to reproduce the issue:

1. Have the alfresco server with CORS enabled and kerberos setup
2. Run the alfresco content app with latest alfresco-js-api from develop branch
3. Observe on the home page user info not displayed on the top right corner on the toolbar.
4. Click on word document and it fails to preview

Component name and version:
alfresco content app

Browser and version:

Node version (for build issues):

I have tested by taking the latest development code of ACA and enabled "withCredentials". Then modified the authguard to enable directly without going to loginscreen. Now I am able to login to the app with kerberos. But I do see below issues.
User Initials are not getting displayed

Content is getting displayed twice (once as bookmark and other as content)
