The following PR introduced an accessibility regression: https://github.com/openshift/console/pull/6522 Moving the modal conatiner inside the app div causes the modal content to be hidden from screen readers. This is because aria-hidden is added to the app div when a modal is display, but this now includes the modal itself. Previously they were sibling elements. It also appears to have caused the following warning in the JavaScript console. Warning: unmountComponentAtNode(): The node you're attempting to unmount was rendered by another copy of React. We should leave the modal container and app element as siblings in the DOM and find another way to address the original problem (bug 1875494) being fixed.

I've used ChromeVox to verify screen reading. I've tested different sections of the page with the plugin in Chrome 89 I've tested the quick-start side drawer with the catalog sidebar, it is working fine. Verified on build version: 4.8.0-0.nightly-2021-05-09-105430
