Xamarin.Forms Editor resizing jitter in UWP project

Question

Why is there a jitter on Editor resizing on a new line?

<ContentPage xmlns="http://xamarin.com/schemas/2014/forms"
             xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"
             x:Class="JitterBugTest.MainPage">

    <StackLayout>
        <Editor AutoSize="TextChanges"/>
    </StackLayout>

</ContentPage>

Also the case when I try manually resize it inside OnTextChanged. But there is no such problem for a regular UWP project using corresponding TextBox class with AcceptsReturn="True".

How can I fix this?
