This was by design. MSVC STL intendedly only enabled changes in P0608R3 sin=
ce
C++20 (https://github.com/microsoft/STL/pull/1629#issuecomment-778895630).

But given the author of P0608R3 applied the changes to libc++ in C++17 mode=
, I
think it makes more sense to treat it as a DR.

I've opened this issue:
