Steps to reproduce

Toggle SSR on and off to see hydration mismatch message

What is expected?

Not to contain hydration mismatch

What is actually happening?

HTML rendered on the server returns component(s) wrapped in comment rather then actual wrapper component. This is why hydration contains mismatches

@edison1105 Can you reopen issue ? Still can see error if pass a list rendering (v-for) to slot, here's demo:
