Nesting non-Text Components in Text is Unsupported

We try to QI the child to xaml::Documents::Inline and fail

void TextViewManager::AddView(const XamlView &parent, const XamlView &child, int64_t index) {
  auto textBlock(parent.as<xaml::Controls::TextBlock>());
  auto childInline(child.as<winrt::Inline>());
  textBlock.Inlines().InsertAt(static_cast<uint32_t>(index), childInline);
}

Can be reproed by clicking on the bookmarks button in the redesigned RNTester when none are present, when trying to render this component.

const EmptyState = () => (
  <View style={styles.emptyContainer}>
    <View style={styles.emptyContainerInner}>
      <Image
        source={require('../assets/empty.png')}
        resizeMode="contain"
        style={styles.emptyImage}
      />
      <View>
        <Text style={styles.heading}>Bookmarks are empty</Text>
        <Text style={styles.subheading}>
          Please tap the{' '}
          <Image
            source={require('../assets/bookmark-outline-gray.png')}
            resizeMode="contain"
            style={styles.bookmarkIcon}
          />{' '}
          icon to bookmark examples.
        </Text>
      </View>
    </View>
  </View>
);

Reproduce the failure by clicking the bookmarks button in the redesigned RNTester when no bookmarks are present, using the EmptyState example in the issue. Start at TextViewManager::AddView and trace the child conversion and insertion into TextBlock.Inlines(); done means this empty state renders without the reported failure.
