The maintainer of magit/forge (tarsius) was unable to reproduce that bug, so I tried my hand at creating a minimal test case, and I was able to get it down to this.

I tracked down the function doing the actual changing: json-encode-alist. I filed https://debbugs.gnu.org/cgi/bugreport.cgi?bug=40693
I still find the behavior here confusing, but I expect it will be considered expected behavior.
