📚 Description

This targets the failing tests in Nuxt's ecosystem-ci, changes in Nuxt prevent the stringifying of $route and prevents hydration from updating/rendering the stringified route. (nuxt/nuxt#28841)

We should consider changing these tests to check the localeRoute results keys instead of comparing the entire object, or figure out how to test its results in unit tests.
