Frame doesn't obey HeightRequest

Question

Can you guys please explain why the Frame doesn't respect the HeightRequest or WidthRequest?

Using those properties in other controls it works as expected.

For example, in this XAML I'm using a Frame and a BoxView:

<StackLayout Orientation="Horizontal"
             HorizontalOptions="CenterAndExpand"
             Padding="10">
    <Frame VerticalOptions="Center"
           HeightRequest="5"
           WidthRequest="5"
           BackgroundColor="Red"/>
    <BoxView VerticalOptions="Center"
             HeightRequest="5"
             WidthRequest="5"
             Color="Blue"/>
</StackLayout>

And the result is:

There is a big difference between the Frame's size and box's size, but it shouldn't have.

Frame has a default padding of 20. Set Padding="0".
