Unable to assign a dynamic schema type

Describe the bug

Consider the following factory

import {
	defineI18nMiddleware,
	detectLocaleFromAcceptLanguageHeader
} from '@intlify/hono';

export function createI18nMiddleware<TSchema extends Record<string, string>>(
	schema: TSchema,
	translations: Record<string, TSchema> = {},
) {
	return defineI18nMiddleware<{ message: TSchema }>({
		locale: detectLocaleFromAcceptLanguageHeader,
		messages: { ...translations, en: schema },
		                                               // ^^ <-- TS error
	});
}

The TS error

Type 'TSchema' is not assignable to type 'TSchema extends LocaleMessage<string> ? TSchema : LocaleMessage<string>'.
  Type 'Record<string, string>' is not assignable to type 'TSchema extends LocaleMessage<string> ? TSchema : LocaleMessage<string>'

Not sure if it's me doing something wrong here.
