typedef-ed ref-qualified function type differs in behavior between gcc and clang

When I try to compile the following code:

struct A {
    void foo() & {
    }
};

int main()
{
    using F = void() &; // or 'typedef void F() &;'
    [[maybe_unused]] F A::*pf = &A::foo;
}

with clang this compiles, but when compiled with gcc it produces an error.

test.cc:9:37: error: cannot convert ‘void (A::*)() &’ to ‘void (A::*)()’ in initialization
    9 |     [[maybe_unused]] F A::*pf = &A::foo;

Which behavior is correct?
