Stretching a RelativeLayout's height with an expandable StackLayout

Hi,

Here is my code:

<RelativeLayout>
    <BoxView Color="#3498DA" HeightRequest="50" RelativeLayout.WidthConstraint="{ConstraintExpression Type=RelativeToParent, Property=Width, Factor=1}"/>

    <StackLayout
        RelativeLayout.XConstraint="{ConstraintExpression Type=RelativeToParent, Factor=0, Property=X, Constant=108}"
        RelativeLayout.YConstraint="{ConstraintExpression Type=RelativeToParent, Factor=0, Property=Y, Constant=53}"
        RelativeLayout.WidthConstraint="{ConstraintExpression Type=RelativeToParent, Factor=1, Property=Width, Constant=-118}"
        VerticalOptions="StartAndExpand">

        <Label Text="{Binding Name}" FontSize="18" FontAttributes="Bold"/>
        <Label Text="{Binding Id, StringFormat='ID: {0}'}" FontSize="Micro"/>
    </StackLayout>
</RelativeLayout>

Note: I used a StackLayout in order to get the ID label systematically following the Name label.

This works fine when Name label is shown on 1 line:

But whenever the name is shown on 2 lines, then basically the RelativeLayout is not stretched enough (red borders show how Xamarin computes the height of the RelativeLayout:

Question: How should I handle this properly?

Remark: Using a RelativeLayout because on the left of the labels there is some graphics, similarly to https://developer.xamarin.com/samples/xamarin-forms/UserInterface/BusinessTumble/
