@JosephWright Sorry for just pinging you, but I saw you're online and even though I searched for some while I could not find an answer on meta. If you have time, could you perhaps look at
tex.stackexchange.com/q/453102/121799. The user refuses to put an MWE because the issue is the same as in a previous question. However, as the previous question does not have an answer, I cannot mark the new question as a duplicate of the old one. What am I supposed to do?
