Research direction
Reproduce the bug using the provided JSFiddle. Examine the v t directive implementation in vue i18n's source (likely in src/directive.js). Investigate why the directive does not update when the locale changes, focusing on how the directive binds to the text node and whether it properly watches for locale changes. Consider if the issue is related to Vue's reactivity system when the directive is applied to a component's root element.
