Fix: nuxt/nuxt@5328404
Sink: <NuxtLink> returns href unsanitized (no isScriptProtocol guard) in packages/nuxt/src/app/components/nuxt-link.ts.
Introduced by: nuxt/nuxt@4cefce4 — "feat(nuxt3): add <NuxtLink> component" (#3544). The unsanitized-href behavior has existed since the component was created.
First released: Nuxt v3.0.0.
