Auto complete doesn't include items from unimported namespaces

_This issue has been moved from [a ticket on Developer Community](https://developercommunity.visualstudio.com/t/Auto-complete-doesnt-include-items-from/10825319)._

---
When typing with "Show items from unimported namespaces" turned on, I get suggestions correctly (with the option in the Intellisense box turned on). When I press ctrl+space to open it, the option button is turned off and therefor I don't get these suggestions. If I restart VS, the first time I press ctrl+space I will get the correct suggestions but then escape, ctrl+space and the option is turned off again.

First time I press ctrl+space:

Second time I press ctrl+space:

Thanks for your feedback! In order to further investigate this issue, I need to confirm something with you. What programming language do you use with your project? (C#, C++, or other)? It would be very helpful if you could provide some screenshots that has this problem.

FYI, still present in VS 2026 Insiders

Reproduce the issue in Visual Studio with "Show items from unimported namespaces" enabled, then press Ctrl+Space repeatedly after dismissing completion. Trace the Roslyn completion behavior responsible for the option state; done when the setting remains enabled and suggestions from unimported namespaces continue to appear.
