I'd bet this is one of those ithngs that regressed with #7243. I can't be sure what the issue we're using for tracking these is - @DHowett help me out?

It's not #8217, but that one suggests

Indeed. This was fixed in #7243, but I have been holding it back from Stable builds because it breaks WOW64 PowerShell. (#7418).

Then got dup'ed to #7243.
