--- Comment #6 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
Confirmed.
A simplier compile time testcase from PR 99152:

void f() {
  float x, &r = x;
  auto l = [=] () {
    static_assert(std::is_same_v<decltype(x), float>);
    static_assert(std::is_same_v<decltype((x)), const float&>);
    static_assert(std::is_same_v<decltype(r), float&>);

    // fails, decltype((r)) is float&
    static_assert(std::is_same_v<decltype((r)), const float&>);
  };
}
