Yes, the issue has status C++17, which is defined (follow the link) as:

"C++17 - (C++ Standard, as revised for 2017) - The full WG21/PL22.16
committee has voted to accept the Defect Report's Proposed Resolution
into the published 2017 revision to the C++ standard, ISO/IEC IS
14882:2017(E)."

The date when an issue was created is not necessarily related to the
C++ standard it will be agreed being fixed. Of-course a C++-Compiler
vendor could decide to consider such a bug fix as something she wishes
to backport to older standards.

None of these links represent the C++ committee, so I don't consider
this information as binding.
