Trying to set a device specific scale on an ActivityIndicator in Xamarin XAML causes a crash

We have a Xamarin.Forms app we are converting from code behind to XAML. I have already used OnPlatform successfully, but it is causing a crash when setting the scale of our ActivityIndicator. I am testing on the iOS simulator. Here's the code:

<ActivityIndicator IsRunning="True" Color="White" HorizontalOptions="Center" VerticalOptions="StartAndExpand">
      <ActivityIndicator.Scale>
        <OnPlatform x:TypeArguments="x:double" iOS="4.0" Android="3.0" />
      </ActivityIndicator.Scale>
    </ActivityIndicator>

In contrast, these two would work:

<ActivityIndicator IsRunning="True" Color="White" HorizontalOptions="Center" VerticalOptions="StartAndExpand">
      <ActivityIndicator.Scale>
        4.0
      </ActivityIndicator.Scale>
    </ActivityIndicator>

-

<ActivityIndicator IsRunning="True" Color="White" HorizontalOptions="Center" VerticalOptions="StartAndExpand" Scale="4.0">
    </ActivityIndicator>

try this

<ActivityIndicator IsRunning="True" Color="White"
HorizontalOptions="Center" VerticalOptions="StartAndExpand">
  <ActivityIndicator.Scale>
    <OnPlatform x:TypeArguments="x:Double" iOS="4.0" Android="3.0" />
  </ActivityIndicator.Scale>
</ActivityIndicator>

it's a Type argument. double isn't really the type, Double is.

Case sensitive on the Type:

Change:

<OnPlatform x:TypeArguments="x:double" iOS="4.0" Android="3.0" />

To:

<OnPlatform x:TypeArguments="x:Double" iOS="4.0" Android="3.0" />

FYI: Enable XAML compiling to catch these during compile time vs. run-time.
