Additional context

Hi. I'm open facebook/mysql-5.6 project and find the above phenomena. Strange, isn't it ? It cannot find rocksdb::TransactionDB, but it surprisingly jumps to Table::Open() within leveldb header in system path instead of telling me No definition Found.

It works well most of time. It just happens in this case.

Could you run the command C/C++: Log diagnostics from the VS Code command palette and share the output? It will show what include paths the IntelliSense refers to.
