    I work on Microsoft Visual C++ testing, where we regularly build popular open-source projects, including yours, with development builds of our compiler and libraries to detect and prevent shipping regressions that would affect you. This also allows us to provide advance notice of breaking changes, which is the case here.

Recently, while running the tests for LLVM, the `Clang :: Format/docs_updated.test` test failed. Please refer to the attached build log for more details:
[docs_updated.test.log](https://github.com/user-attachments/files/18090961/docs_updated.test.log)

Repro steps:

1. Open x64 native tools command prompt for VS2022
2. git clone https://github.com/llvm/llvm-project.git
3. mkdir llvm\llvm-project\build_amd64 & cd llvm\llvm-project\build_amd64
4. cmake -G "Visual Studio 17 2022" -A x64 -DCMAKE_SYSTEM_VERSION=10.0.22621.0 -DLLVM_ENABLE_PROJECTS="clang" ..\llvm 2>&1
5. msbuild /m /p:Platform=x64 /p:Configuration=RelWithDebInfo /p:PreferredToolArchitecture=x64 LLVM.sln /t:Rebuild 2>&1
6. python.exe ../llvm/utils/lit/lit.py -v --no-progress-bar --param build_mode=RelWithDebInfo --param clang_site_config=./tools/clang/test/lit.site.cfg ./tools/clang/test -j 16 --filter Format/docs_updated.test
