This is also in preparation of adding more of them IIRC.

Does this function need to be public? Also let's to annotate the overridden functions with OVERRIDE. (comments not repeated on all the other table renderers)

Correcting the comment.

Doing the OVERRIDE now. It needs to be public since it will be called from the otherAnonymousBlock as otherAnonymousBlock->createAnonymousBoxWithSameTypeAs(parent).

Nit: "more derived" was like deeper class hierarchy in my first reading, I would just re-arrange the wording: in the future extend to more classes derived from RenderBox.

Let's add a comment about why we did that: the current switch case situation was going to be messy as we will need to mix cases that were very dependent on the class so it made sense to add a virtual function.

If you are exposing this function in the derived class, we may as well expose this one. It's unfortunate that we have to but I see your point.
