I also found that it when the span with Italic attribute the FontSize of Label can not work. However , I found a WorkAround for this , you can set FontSize of this Span to solve it .

Have a look at follow code:

<StackLayout Margin="20,35,20,25">
    <Label FontSize="50" TextColor="Blue">
        <Label.FormattedText>
            <FormattedString>
                <Span Text="underlined text" TextDecorations="Underline" />
                <Span Text=", emphasized" FontSize="50" FontAttributes="Italic" />
            </FormattedString>
        </Label.FormattedText>
    </Label>
</StackLayout>

The effect :

I think next version of Xamarin Forms will fix it as soon as possible .
