A question within a question o3o
It seems like the comment somehow became a semi-question, and the link is named. It's not possible to edit it either, to see the raw text.
Just a bit curious, it must be a glitch on the site.
Back when the PokeBase was fairly new, there was a system where the site would post a little message on an answer when a question similar to the one the answer answered is asked. If you click on the link in the comment, you'll see that the question got "related to answer for ____" edited in, and no edit history, which means the site edited it in. That system was removed.
This is how it works. I guess the thing wasn't removed
