My thinking is that to someone reading this code without the context of this bug, the reason for the assert isn't clear.  If you could add a comment as to why or change the name of the function [e.g. resolveDirectionality()] it may be easier to understand this.

The point I find confusing is that it looks like this is the canonical way to get the directionality of an HTMLElement, whereas it's only useful for dir=auto.
