[NavigationTiming2] Mistake in code example

In http://www.w3.org/TR/2013/WD-navigation-timing-2-20130131/ there is a
mistake in the second code example in the Introduction section:

var navigationTiming = performance.getEntries("navigation");

must be

var navigationTiming = performance.getEntriesByType("navigation");
