Syntax highlighting breaks down after declaring raw multiline text

[Drovosek01]

Checklist

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

The code with a problem is:

#include <iostream>
#include <vector>
#include <string>
#include <mach-o/dyld.h>
#include <mach-o/nlist.h>
#include <mach-o/loader.h>
#include <sys/mman.h>
#include <mach/mach.h>
#include <cxxabi.h>
#include <libkern/OSCacheControl.h>
#include <sstream>



#define RAW_DATA_STRING X(R"(
B801000000C3
B801000000C3
B801000000C3
)")

static std::string trim(const std::string& s)
{
    size_t start = 0;
    while (start < s.size() && std::isspace((unsigned char)s[start]))
        start++;

    size_t end = s.size();
    while (end > start && std::isspace((unsigned char)s[end - 1]))
        end--;

    return s.substr(start, end - start);
}
    

It looks like:

It should look like:

After a multiline text with define R"()", the syntax should be recognized correctly, but the grammar parser recognizes and highlights everything below as just text, not code.
