Call structure pointer member completion error in macro

[ArtisticZhao]

Observed behavior

But when i call a member of sturct pointer (like np->a). The completer will add the -> to the header of .c file. It only happend when I try to complete the member of the struct pointer in the Macro functions. Here the screenshot will show the behavior clearly.

The configuration of ccls:

{
    "languageserver": {
        "ccls": {
            "command": "ccls",
            "filetypes": [
                "c",
                "cpp",
                "cuda",
                "objc",
                "objcpp"
            ],
            "rootPatterns": [
                ".ccls",
                "compile_commands.json"
            ],
            "initializationOptions": {
                "cache": {
                    "directory": "/tmp/ccls"
                },
                "client": {
                    "snippetSupport": true
                },
                "highlight": {
                    "lsRanges": true
                }
            }
        }
    }
}

The file i test the bug.

#include <stdio.h>

#define add(x,y)    ((x)+(y))
int addf(int x, int y){
    return x+y;
}
int main(int argc, char *argv[])
{
    struct num {
        int a;
        int b;
    };

    struct num n = {
        .a = 1,
        .b = 2,
    };
    struct num *np = &n;
    np->a = 2;
    addf(np->a, np->b);
    add(np->a, np->b);
    return 0;
}

Expected behavior

The expected behavior is when I try to complete the member of struct pointer in a macro function, will same as the completion in normal funciton.

Steps to reproduce

In the macro function, call a struct pointer member list use '.' and select a member and use enter to complete.
