[iOS] Ellipsis carries background from trimmed text

Description

This issue happens on iOS only:

I tried to use nested text which has background, and could be wrapped with an ellipsis. Even the nested text doesn't show, the ellipsis has the background of nested text.

<Text numberOfLines={1} ellipsizeMode={'tail'}>Long text <Text style={{backgroundColor: 'red'}}>Nested text</Text></Text>

Steps to reproduce

<Text numberOfLines={1}>Long text <Text style={{backgroundColor: 'red'}}>Nested text</Text></Text>

Just create a long text with colored nested text, check the behavior of ellipsis.

Snack, code example, screenshot, or link to a repository

<Text numberOfLines={1} ellipsizeMode={'tail'}>Long text <Text style={{backgroundColor: 'red'}}>Nested text</Text></Text>

iOS 上で、提供されている React Native の再現ケースから始めます。赤い背景と末尾の省略記号を持つ、1 行のネストされた Text です。iOS のテキスト描画および切り詰め処理の経路を追跡し、切り詰められたネストされたスタイルが省略記号に影響する理由を特定します。再現ケースが引き続き正しく切り詰められ、かつ省略記号が非表示のネストされたテキストの背景を持たなくなれば完了です。
