I did a meta search (of course skipping the help section, duh) for "frame challenge" and did not find any direct answer. There was only a post about not meeting the "justified frame challenge" criteria, which was not elaborated on.
On Parenting, a site on which I was formerly a mod, frame challenges are not allowed unless they also answer the question in a helpful way.
This question has a very helpful but slightly frame challenging answer (which I upvoted, because it's well supported and completely correct), but the OP recognized it as "not an answer." The problem is that there is no non-frame-challenging answer because the problem is not what the OP imagines it might be, so asking for a specific answer will only address symptoms of cyanide poisoning, which the answer provided.
Which leads to the question asked. Thank you. (Now I'll go read the help section.)
