Receiving SEC7118 warning in console, but resource loads and contains Acess-Control-Allow-Origin header

Hello,

I'm receiving the SEC7118 warning in the console.  However, the resources do load properly (I do not have this overriden), and when I inspect the request in the f12 network tab, the Access-Control-Allow-Origin header is present with the correct value.

Any idea on why these messages are appearing with the headers present?  I find it odd that the resource still completes, and it is a credentialed request.
