alicerunsonfedora I've found that once tabs are in this "double open" state sometimes it result in other strange tabs behavior, e.g., opening a link open extra tabs that were previously closed or duplicated content, or reloading a page resulting in a new page.
The only way to get out of this state is to close all tabs (using touch), kill the app, and reopen. I didn't include these details in the report since it's a bit trickier to reproduce. I've found the only way to use Orion on iPadOS in current form is to not use it with external keyboard at all.
