I have the same problem in Opera One(version: 102.0.4880.16). On the website https://www.sync.opera.com in the 'open tabs' tab there is a copy of the tabs from the currently used context. If you change the context, the tabs on the page will also change to those in the current context. In my opinion, there should be copies of all tabs from all contexts, dynamically changed depending on the user's actions, i.e. adding or deleting them in any context. For me, this is a big mistake of Opera.
