Looking through the code and PR2448 more closely, the resolution to that PR, db5f2ae, only addressed the html output of the renderer. So I guess this substitution would also need to be applied to text_part?
Unless I hear otherwise, I’ll make a PR to that effect once I get an environment set up to verify the change.
(I suppose any change will take some time to be deployed on Standard, even if accepted… So I’ll ask the user to apply that regex locally for now if they want to use a text-only viewer)
