Additional context

No response

Start by reproducing the difference between #fun and @fun in the MultiRootProjects workspace, using project_A\project_subfolder_H\ references.cpp and the linked test repository. Compare the workspace and file symbol-search paths and their displayed results; done means both searches show consistent entries while navigating to the same code line.
