Chrome CORB Blocking Response?

[#1]

Device: Mac 10.12.3

Browser: Chrome 73.0.3683.103

Target: at.js 1.7.1

Target Activity:  uses Conversion goal measured by Click of Element (set within Goals & Settings)

Problem:  With active test on click of selected element, Chrome blocks response (CORB)

Cross-Origin Read Blocking (CORB) blocked cross-origin response https://mboxedge17.tt.omtrdc.net/m2/crocs/mbox/json?mbox=clicked-btn-x&mboxSession=b1268b31051b407ea... with MIME type application/json. See https://www.chromestatus.com/feature/5629709824032768 for more details.

NOTE:  I see the same issue when using getOffer/applyOffer.

Concerns:

• Is Target processing click events correctly?
• Is Target processing getOffer/applyOffer. correctly?
• When using getOffer/applyOffer if CORB blocks the response, will the offers not be returned, preventing the experience? (Haven't had time to try)
• Do other browsers cause same issue?

Chrome's CORB algorithm seems to be fickle.  For some reason it doesn't block a JSON response when I use the getOffer method, which is practically the same thing as the JSON response when using the Measure by click element.
