Header file with duplicate name but unique directory not identified by intellisense

在不同项目中放置重复的 Resources/common.h 文件，以复现报告中的布局，然后在比较 ProjectA/SourceA.cpp 和 ProjectB/SourceB.cpp 的同时检查扩展的 IntelliSense 诊断和调试日志。跟踪扩展如何识别并索引 header：此时 go-to-definition 可以成功，但标识符仍无法解析。完成标准是两个项目本地 header 都已建立索引，并且引用解析时没有红色波浪线。

Bug Summary

I am using VSCode to work on source files from a large Visual Studio solution with many projects. Each project has its its own directory with various source files, and a subfolder for resource headers.

Solution/
├─ ProjectA/
│ ├─ Resources/
│ │ ├─ common.h
│ ├─ SourceA.cpp
├─ ProjectB/
│ ├─ Resources/
│ │ ├─ common.h
│ ├─ SourceB.cpp

ProjectA/Resources/common.h will only ever be referenced by source files within the ProjectA directory.
The issue with this is each of these resource headers has the same filename, so the intellisense database will only process the first one it finds. This is usually the first project folder alphabetically.
When running intellisense, on the above example, references to ProjectA/Resources/common.h by ProjectA/SourceA.cpp are resolved.
References to ProjectB/Resources/common.h by ProjectB/SourceB.cpp are not resolved and result in red squiggles with "identifier XYZ is undefined"

However when I click on the identifier in Source.B and select "go to definition" the extension correctly opens ProjectB/Resources/common.h and jumps to the selected identifier.

Configuration and Logs

This behavior is found in the default configurations. I have not been able to find a change to the configuration that alters this behavior.

Debug log diagnostics do not display anything unusual or useful.
