unused-includes: Problem with forward declared types

[megyerib]

When a type is forward declared in a header, and declared in another, clangd marks the declaration's header unused, even if it is required. This is a minimal code I could reproduce the error with:

main.c

#include "decl.h"  /* Included header decl.h is not used directly (fix available) clangd(unused-includes) */
#include <stdio.h>

void print_container(container_t* container)
{
    printf("%d\n", container->data);  /* decl.h is needed because of this member access, fwd.h is not enough */
}

int main() {
    container_t container = {5};
    print_container(&container);
    return 0;
}

fwd.h

#ifndef FWD_H
#define FWD_H

typedef struct container_t container_t;

#endif

decl.h

#ifndef DECL_H
#define DECL_H

#include "fwd.h"

struct container_t {
    int data;
};

#endif
