From 4.11.8 before 4.12.27, hono/jsx did not isolate context values per request during server-side rendering, allowing createContext, useContext, jsxRenderer, or useRequestContext data from a different in-flight request to be used after an await in an async component. This issue is fixed in version 4.12.27."

Desde la versión 4.11.8 antes de la 4.12.27, hono/jsx no aislaba los valores de contexto por solicitud durante la renderización del lado del servidor, permitiendo que los datos de createContext, useContext, jsxRenderer o useRequestContext de una solicitud en curso diferente fueran utilizados después de un await en un componente asíncrono.
