Here's a snippet of the juicy bit:

<NuxtLink v-slot="{ href }" to="/foo" custom>
  <a :href="href">Here's a link</a>
</NuxtLink>

Describe the bug

When using a NuxtLink component with custom attribute, a warning is logged.

Additional context

In RC 8 it was working fine, my suspicion is that the new link prefetching feature is to blame.

Suspicious line of code: https://github.com/nuxt/framework/blob/v3.0.0-rc.10/packages/nuxt/src/app/components/nuxt-link.ts#L229

Maybe worth to mention, a workaround is to use vue router's RouterLink component directly instead of NuxtLink

Logs

[Vue warn]: Extraneous non-props attributes (class) were passed to component but could not be automatically inherited because component renders fragment or text root nodes.
