Cannot interact with web content using the Voiceover screenreader. Running latest MacOS 13, MacBook Pro 16 inch M1. To reproduce, first enable VoiceOver, then open a website in Orion. Then using the coiner navigational commands (ctrl + option + left / right arrows), navigate the window until you hear the URL of the website followed by the word "group". Interact with that group with ctrl + option + shift + down arrow, and try to navigate the web content. Voiceover reads nothing.
This does not change in compatibility mode. Could this perhaps be due to the type of interface element you're using? Voiceover doesn't recognise the page content as a "web content" area, but a "group" and therefore doesn't render it as a webpage.
