Inconsistent Syntax Highlighting in defines between C and C++

[joaomspires]

Checklist

• This problem exists even with the setting "C_Cpp.enhancedColorization": "Disabled"

If Disabling that^ makes the problem go away, then follow this to make an issue on the C++ extension:
https://github.com/microsoft/vscode-cpptools/issues/new/choose

The code with a problem is:

#ifndef ERIS_MACROS_TYPE_CASE_H
#define ERIS_MACROS_TYPE_CASE_H

#define ERIS_TYPE_CASE(A, B) switch ((eris_U64)((A).type) | ((eris_U64)((B).type) << 8)) {
#define ERIS_TYPE_WHEN(A, B) case (eris_U64)(A) | ((eris_U64)(B) << 8):
#define ERIS_TYPE_ELSE       default:
#define ERIS_TYPE_END        }

#endif

It looks like:

In C:

In C++:

Theme used: Default Light Modern

It should look like:

I expected the syntax highlighting in C to match that of C++.

Also, the parentheses in MY_CASE and ERIS_TYPE_WHEN are colored differently because the switch braces are in two separate macro bodies.
