Describe the bug

I have a project that uses cmake and precompile headers (.pch). I uploaded a .zip of my project and when I try to build the compiler complains that it can't find the .pch. Sure enough prefix.pch is missing from the list of files in the Tree, but the file is definitely in the .zip. I've attached a small sample .zip. Here is the output when I try to build using gcc-14.1.0, but similar errors occur with other compilers like clang & icx:

Workaround: create a new source editor, copy/paste the contents of the .pch into it, rename it prefix.pch, and include it into the Tree.

Steps to reproduce

• Visit godbolt.org
• Switch to Tree mode
• Project Button Menu -> Choose File
• Select the attached .zip
• Click Upload

Expected behavior

Expected: the .pch in the .zip should be in the list of files in the Tree
Actual: the .pch in the .zip is missing from the list of files in the Tree
