Cannot debug in Chrome 80 Inspectable web elements not available
Several developers have complained that Chrome 80 breaks debugging for CEP panels, with errors like "document.registerElement is not a function". If you are facing this problem, try @justin2taylor's suggestion:
Use the CEF Client provided with each CEP Version on the Github. For CEP 9, use this one: https://github.com/Adobe-CEP/CEP-Resources/tree/master/CEP_9.x
