[BUG] Not setting the Height property for the Relative panel can cause the application to freeze and crash

[GID0317]

Describe the bug

When I was updating the Relative Panel in the gallery app to match the WinUI3 gallery, I noticed that if we don't set the height for the Relative Panel, it causes the application to freeze and crash. I'm not sure if this issue is specific to the gallery application, but I think it's worth investigating

<ui:RelativePanel Width="300" >
            <Rectangle
                x:Name="Rectangle1"
                Width="50"
                Height="50"
                Fill="Red" />
            <Rectangle
                x:Name="Rectangle2"
                Width="50"
                Height="50"
                Margin="8,0,0,0"
                ui:RelativePanel.RightOf="Rectangle1"
                Fill="Blue" />
            <Rectangle
                x:Name="Rectangle3"
                Width="50"
                Height="50"
                ui:RelativePanel.AlignRightWithPanel="True"
                Fill="Green" />
            <Rectangle
                x:Name="Rectangle4"
                Width="50"
                Height="50"
                Margin="0,8,0,0"
                Fill="Yellow"
                ui:RelativePanel.AlignHorizontalCenterWith="Rectangle3"
                ui:RelativePanel.Below="Rectangle3" />
        </ui:RelativePanel>
