What ensures that this cast to toElement is safe ?

minor issue s/result/before.

Also, there is lot of different names used in the code like result, renderer, before, etc. I would prefer a consistent naming like beforePseudoElementRenderer and afterPseudoElementRenderer

If you look at the rest of that function you can see that renderer is the result of sibling->renderer() and sibling is an Element. The way that function is written is bad because it overwrites sibling right before this check so we need to do renderer->node() to get a reference to the original sibling.
