Comment 5 for bug 1557259

as shown by Pierre's analysis above, this is a bug in the html generator that is part of qdoc.
So all documentation pages will have it, because they're generated using the same tool.

If you read Pierre's comment, he also mentions that the bug is already fixed in the upstream qdoc tool in Qt 5.6, and also links the commit that fixes the bug.

We only have to take that commit and apply it to our version of qdoc, since I guess it will still take a few months before we move to Qt5.6 (which is not even released yet).

I hope that's clearer :)
