This can be shown by creating a template with a few sections, then transcluding
it into a new page (i.e. a new user's talk page)
If these were wiki sections, then if the newbie clicked the edit links on their
page, they would edit the template, which would not be desired. If these are
HTML sections, the links would instead point to the transcluding page;
presumably a bug, but seems like what they'd expect in this case.
But if it's a new page, those sections won't exist, so any edits to them will
just be silently discarded.
Ideally, either these should be appended to the end, or the edit link should
give an error.
