structuredClone coerces rejected values while creating DataCloneError

Description

The React Native structuredClone polyfill interpolates rejected values into its error message. That invokes user-defined coercion such as Symbol.toPrimitive; a non-cloneable function or WeakMap can therefore replace the required DataCloneError with an arbitrary user-thrown error.

Expected behavior

Rejecting an unsupported value should produce DOMException / DataCloneError without executing user coercion hooks. The non-standard message does not need to include the rejected value.

React Native Version

0.87.1 and current main

Affected Platforms

JavaScript runtime - All

まず React Native の structuredClone polyfill と DataCloneError を生成する経路を特定し、次に Symbol.toPrimitive が例外をスローする拒否された値で問題を再現します。未対応の値が、ユーザー定義の型強制を呼び出すことなく、一貫して DOMException/DataCloneError を生成すれば完了です。
