Bug report: comments appear as listed in the the original topic for a moved question - "?"

I've found an interesting bug some time ago. Here what it looks like.

I'll use my most recent example. A student posted a question yesterday in the Balancing chemical equation topic. I answered it and moved it to the more appropriate Molarity topic.

Now comes the fun part. When a comment is posted on the question, it appears on the Chemistry page as being posted in the original topic of the question, not in the current one.

So, I answered the question and moved it to Molarity. Later, when I posted a response to the student's "thank you" note, here's how it looked like

Like I've said, this is not something new, so I don't know if you guys know about it.

I have experimented with a few questions this way and the result is always the same #-># the answered question appears in the correct topic, after it was moved, but later comments appear in the original topic.
