Align closing chevron with associated tag

Is your feature request related to a problem? Please describe.

<RadioButton
    Grid.Row="1"
    Grid.Column="1"
    GroupName="MyOptions"
    IsChecked="{Binding Foo}"
    >
    My label
</RadioButton>

<SomeOtherExample
    attribute="value"
    />

The alignment of > and "My label" is confusing. The text is nested within the element, it should be visually distinct with indentation.

Describe the solution you'd like

> and /> should be aligned with the < when they are on separate lines. > is more closely related to the < as a markup for the element, than it is to the attributes.

<RadioButton
    Grid.Row="1"
    Grid.Column="1"
    GroupName="MyOptions"
    IsChecked="{Binding Foo}"
>
    My label
</RadioButton>

<SomeOtherExample
    attribute="value"
/>

This visually separates the attributes with the content.

Describe alternatives you've considered

Forcing prettier to format xaml by telling it its HTML, but I don't trust that this won't break some xaml-isms that don't quite match HTML.
