Error Thrown When Keyword "link" Used As I18n Key

[TNGD-YQ]

Reporting a bug?

const messages = {
  en: {
    test: "hello",
    "test.link": "world",
  },
};

// 2. Create i18n instance with options
const i18n = createI18n({
  locale: "en", // set locale
  fallbackLocale: "en", // set fallback locale
  messages, // set locale messages
  // If you need to specify other options, you can set other options
  // ...
});

In case above, as u can see our team is using the message key in form of "a.b.c.d", instead of nested object.
When we upgrade vue-i18n from v9.2.2 to latest version 9.8, we noticed a lots of breaking changes, which is expected according to the release notes.

But there is one issue cannot be explained. Error thrown when the message key end with "link", such as "test.link".

vue-i18n.js?v=a4320ed3:2863 Uncaught (in promise) TypeError: String.prototype.link called on null or undefined
    at link (<anonymous>)

Expected behavior

No error thrown.
"link" is not a keyword, it should be allowed to use.
