Orion remembers browsing history from private tabs after updating to release 0.99.123.2. Previously opened links from private browsing will autofill into the address bar in normal browsing even after quitting Orion/rebooting. Recently updated from Monterey to Ventura 13.2.1, but this wasn't an issue before 0.99.123.2 (14" MacBook Pro, M1 Pro 8/14 core SoC).
