FYI, I downloaded and tested each version of Orion for this issue on Catlina and found it only started for me with the Jan 1 RC. I have no problems with this on Catalina with "Version 0.99.126.4.1-beta (WebKit 618.1.2) Build date Dec 14 2023". But I hit the issue starting with "Version 0.99.126.4.1.3-rc (WebKit 618.1.7) Build date Jan 1 2024"
Alternatively I notice the RC don't share the same profiles, etc as the Beta. Could it be not so much the browser/engine but the RC releases are not finding something they need? Note I did test for the issue in the RC after a Reset Orion but it didn't make a difference.
Otherwise the obvious difference between the Beta and thh RC is the Webkit -- 618.1.2 in the last Beta that worked while the issue appears starting with the RC with 618.17 and continues through the RC with 619.1.1.
