[clang-tidy] when try to use code action to fix the function pointer not initialized problem, clang-tidy add =nullptr to the wrong place

[LXYan2333]

code example:

int main() {
    void(*f)(void*);
}

the function pointer f is not initialized, and clang-tidy suggest to add =nullptr to initialize it. but clang-tidy add it to a wrong position:

code example from @HighCommander4

$ cat test.cpp
int main() {
    void(*f)(void*);
}

$ clang-tidy --checks=cppcoreguidelines-init-variables --fix test.cpp
Running without flags.

$ cat test.cpp
int main() {
    void(*f = nullptr)(void*);
}

expected behaviour:

int main() {
    void(*f)(void*)=nullptr;
}
