Thank you for creating the issue! One of our team members will get back to you shortly with additional information.
Thanks @fghzxm for reporting this issue. I have opened a linked issue https://github.com/dotnet/csharplang/issues/2386 in the correct repository.
I believe this issue reflects a bug in docs.microsoft.com's Markdown rendering, not errors in a specific Microsoft product's documentation. Please re-open this thread and close dotnet/csharplang#2386. Also do not open an issue at dotnet/docs.
Just to close the loop here. @fghzxm you're right that this was the right place to open this issue.
@sudeepku if you can reopen this one, I can then close the one that was later opened on dotnet/docs.
But I managed to get ahold of the dev team internally and we do have an internal work item tracking this fix: https://ceapex.visualstudio.com/Engineering/_workitems/edit/79880.
