This is working as originally intended. Using the search action from the unified inbox won't limit the search to folders included in the unified inbox. It will search all downloaded messages.

Changing the behavior after so many years would probably disrupt the workflows of many users. So I don't think we should do that right now.

Dealing with this could be part of a larger search overhaul. The current behavior would be less confusing if the search view displayed where search results came from (a particular folder of a particular account vs. all folders of all accounts).

Once we display that information, we could also change the behavior when starting a search from the unified inbox. It would still disrupt workflows. But at least users would be able to easily notice the behavior change.
