Border can't be applied to nested <Text> components

Description

I'm rendering several Text components wrapped inside a parent Text component, like so:

<Text>
  <Text>text 1</Text>
  <Text style={{ borderWidth: 1, borderColor: 'red' }}>text 2</Text>
</Text>

I'm expecting "text 2" to have a red border, rendering inline along with "text 1". However, the border is not rendered.

If I change the container from Text to View, the border renders properly. However, there are scenarios where this is not feasible (e.g.: rendering inside a TextInput.

This issue was previously opened here and, arguably, wrongfully closed. The reason it was marked as closed was:

Nesting a Text component within a parent Text component is not supported.

However, the documentation clearly states the opposite:

Nested text

Both Android and iOS allow you to display formatted text by annotating ranges of a string with specific formatting like bold or colored text (NSAttributedString on iOS, SpannableString on Android). In practice, this is very tedious. For React Native, we decided to use web paradigm for this where you can nest text to achieve the same effect.

Steps to reproduce

Nest one Text element inside another, applying a border width/color to the nested element.

<Text>
  <Text>text 1</Text>
  <Text style={{ borderWidth: 1, borderColor: 'red' }}>text 2</Text>
</Text>

リンクされた Expo Snack の再現コードと、ネストされた Text に関する React Native のドキュメントから始め、Android と iOS でネストされた Text のスタイルがどのように処理されるかを追跡します。Issue のケースを再現し、borderWidth と borderColor を指定したネストされた Text が、既存のネストされた Text の動作を壊すことなく、親 Text 内部にインラインでそのボーダーを描画することを確認します。
