this code looks like it's cross platform (i.e. we call ResourceBundle in 4 other
places that are platform-independent). I'm not sure why there's a separate
Shell::PlatformResourceProvider function per platform, it seems there should
just be one only and this code is all shared.

nvm, juts saw that Windows is the only one that has a non-empty function:
GetRawDataResource(::GetModuleHandle(NULL), key)

I wonder if we had this code instead if it would work on Windows?

just tried this on Windows, and it worked. here's a patch based on this:

+    return html_data;
+  }
   return base::StringPiece();
 }
