It seems to work for me, but at least one report of strikethrough formatting not showing. May be that I only doesn’t work on macOS 11 which I don’t have for testing. Anyway, if you’ve got a moment please let me know if it’s working for you, and what version of macOS you are using. Thanks!
Edit: Tracked this down to not working on macOS 11, but working elsewhere.

Not sure if this is just a quirk of my particular system – (strikethrough had been visible in some earlier builds)
