TableView Section Title Not Appearing

Creating a TableSection without a title parameter seems to disable the rendering of any TitleProperty text set on the TableSection after it's initialization. If I pass in an empty string to the TableSection constructor and then set the TitleProperty of the section it displays the TitleProperty text just fine.
Is this intentional or is it a bug? It seems strange to me that setting a display property would depend on an initialization value.
Also it might be that this is already fixed, since I'm still on Xamarin.Forms 1.2.2 prerelease 3.
