C++ colorization broken by strings with special characters in enums

[alexr00]

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:

//Plaintext
#include <cstdint>
#include <bit>
using uint32 = uint32_t;

enum class OperatorID : uint32 {
	UNEFFECTED = 0,

	EOS = std::bit_cast<uint32>(";\0\0"),

	COMMA = std::bit_cast<uint32>(",\0\0"),

	LINE_CMNT = std::bit_cast<uint32>("//\0"),
	BLOCK_CMNT_OPEN = std::bit_cast<uint32>("/*\0"),
	BLOCK_CMNT_CLOSE = std::bit_cast<uint32>("*/\0"),

	LIST_CLOSE = std::bit_cast<uint32>("}\0\0"),

	EFFECTED = 1,
};

It looks like:

It should look like:

The strings should be highlighted as strings.
