I have just got Orion into a state where you can't switch tabs,
(As usual this is after the Mac slept)
I closed a few (30?) tabs by use of close tree and close tab.
Then left with two tabs.
But I can't switch between them - see video
This is the first time I have seen this failure.
When I closed and reopened the Orion profile - it only showed the one tab, the one that is displayed in the video.
I would note that Orion seems to be getting worse over time and not improving, especially with tab management.
I can choose either tab.
