[C++20][Modules][clang-format] Incorrect format for `export import </>`

[kilasuelika]

I'm using clang-format 15. Recently I find that if I write

export import <Eigen/Core>;

Then clang-format will incorrectly convert it to

export import <Eigen / Core>;

Extrac space will trigger compilation error. If I only use import <Eigen/Core>; then it will be OK.

Full code will be:

export module MyLib;

import std.core;
using namespace std;

export import <Eigen/Core>;
