Cannot affect the Font of an ExtendedEntry

Let me know if posts about Xamarin.Forms.Labs should be elsewhere.

The Font property on the ExtendedEntry doesn't change anything at all when I test it on Android.

This is what we tried:

<controls:ExtendedEntry Text="{Binding Username, Mode=TwoWay}"
                        Placeholder="Username"
                        Font="Large" />

PS: The documentation examples use ExtendedLabel, I think that may be a minor mistake.
