Hey there,
I am really sorry for the delay of this reply as it is a weekend for us here.
What I can see your screenshot is shown during editing process right? If that is the case, actually that is correct behavior when you edit the comment, it will only show the code similar like 'quote'. Once you save again, it will convert to show the correct content without the code.
Or do you mean this only happen after edit comment save? Because I did tried in my locally, it seems fine for me.
Perhaps you can try replicate this on your licensed support domain and see if you still can manage to replicate the issue so you can update your licensed domain site backend and FTP access at
