And it should, although 1.8 is unsupported - the reason 1.6 is mentioned is because it is the current LTS release, so many packages test against it.
I’ve confirmed there’s an issue on 1.8, but to be honest it’s unlikely that any of the maintainers (of which I am a very part-time one) will put time into fixing an issue on an older Julia version, especially given the new LTS will likely be 1.10 in the very near future.
