Can't create a new diagram with IE 11

[ane-gabriela]

Steps to reproduce:

1. Access the Diagrams app from the Applications panel
2. Click on the Create button
3. Add a title then click Create
4. Add a/some shapes
5. Click on Save & View

Expected results: The diagram is created.

Actual results: A message box appears informing the user that "This request contains an invalid authentication information".

If the user clicks on the Yes button in the information box, the page appears as Saved but as a simple page.

The Diagram appears as a SVG in the attachments.

In the XWiki console:

Environment: Windows 10, IE 11, XWiki 13.8, Diagram Application (Pro) 1.17

NOTE: The creation of a diagram is not working on XWiki 13.7, 12.10.9 either.
It is working with Chrome, FF, Edge.

Officially about IE11 The Internet Explorer (IE) 11 desktop application ended support for Windows 10 semi-annual channel on June 15, 2022. Customers are encouraged to move to Microsoft Edge with IE mode.

The issue is irrelevant.
