Fixes #3840 by reverting #3773. We'll need to reactivate #3572.

The revert had a trivial merge conflict in tests/std/test.lst.

I'm adding test coverage for the #3840 scenario, and I've verified that it fails before the revert. The affected product code is C++14, but I've chosen to make the test C++17 so I can call filesystem::remove() on the temporary file for cleanliness. There's no real loss of test coverage here.
