Is <ui:include> fixed in JSF 2.2?

Question

I remember in JSF 2.1 the <ui:include> was a taghandler, as such, it was evaluated once when the component tree was built. When the src attribute changed before rendering, the page was always rendered using the previous value.

<h:form>
  <h:inputText value="#{sessionScope['includedPage']}" />
  <h:commandButton />
</h:form>

<!-- src should be evaluated before applying values to model phase -->
<ui:include src="#{sessionScope['includedPage']}" />

However with WildFly, the above example just works, the rendered page always include based on the most recent value of includedPage. Why is that? Or do I remember wrong? I didn't find anything in the JSF 2.2 spec regarding this change...
