This behavior is introduced in 2.059beta by:
https://github.com/D-Programming-Language/dmd/pull/874

As far as I know, the main purpose was to avoid breaking existing code:

struct S {
  bool opEquals(const ref S rhs) { ... }
}
void main() {
  S s;
  assert(s == S());  // translated to s.opEquals(S())
}

But, I believe the behavior should be *fixed*.
