The -MD -MF options will generate **circular** dependency when specifying -Fh without -Fo

Description
The -MD -MF options generate circular dependency when specifying -Fh without -Fo

Steps to Reproduce

Here is my compile command to generate the dependency file

"dxc" -Od -Zi -Qembed_debug -T vs_6_8 -MD -MF "_internal_full_screen_transfer_vertex.d" -Fh "_internal_full_screen_transfer_vertex.inl" -Vn "full_screen_transfer_vertex_shader_module_code" "full_screen_transfer_vertex.sl"

And I have the following generated dependency file

full_screen_transfer_vertex.sl: full_screen_transfer_vertex.sl full_screen_transfer_pipeline_layout.sli brx_define.sli

The make error output

make: Circular full_screen_transfer_vertex.sl <- full_screen_transfer_vertex.sl dependency dropped.

But if I change my command to -Fo instead of -Fh

"dxc" -Od -Zi -Qembed_debug -T vs_6_8 -MD -MF "_internal_full_screen_transfer_vertex.d" -Fo "_internal_full_screen_transfer_vertex.inl" "full_screen_transfer_vertex.sl"

I get the correct dependency file

full_screen_transfer_vertex.inl: full_screen_transfer_vertex.sl full_screen_transfer_pipeline_layout.sli brx_define.sli

Actual Behavior

The make error output

make: Circular full_screen_transfer_vertex.sl <- full_screen_transfer_vertex.sl dependency dropped.

Environment

• DXC version: dxcompiler.dll: 1.8 - 1.8.2405.15 (fd7e54bcd); dxil.dll: 1.8(101.8.2405.17)
• Host Operating System: Windows 10 Pro 22H2 19045.5247

Start by reproducing the shown dxc command with -MD -MF -Fh and compare its dependency output with the -Fo case. Trace the dependency-generation path handling the -Fh and -Fo output options. Done means the generated dependency target names the header output rather than the input .sl file, without introducing a circular dependency.
