Previously, declarations that are not available in the global namespace, such as member functions of a class, would also appear in the autocomplete suggestions list. To fix this, we now only recurse into scopes of namespaces and classes when fetching declarations if we want to retrieve all the available declarations in the document (For the use of Locator & ClassView).
