This question of mine was just closed as unclear. I haven't really received any feedback as to what people find unclear. One user said they didn't understand the question and suggested to rework the title, but that's not really much for me to go off.
Of course this is totally fair. It is very common to know you don't understand something, but to not be able to explain why. Noone owes me that explanation.
So I am taking what I view as the next step, and asking a broader audience. How do I clarify my question?

, for example. Personally, I would have left a comment initially rather than voting immediately to close. On the other hand, you're not new to the site, so people probably think you've been asked to include a minimal working example before.
