The .properties attribute "must return an HTMLPropertiesCollection rooted 
at the Document node, whose filter matches only elements that have 
property names", which further filters the results of the algorithm. 
Similarly, everything that uses the algorithm here does things "for each 
property name", so if itemprop="" doesn't have any tokens, nothing happens 
and it doesn't matter that the algorithm returns it.
