If you just want to work around the issue for now, you can use v-show.
Since v-if removes the allow-mismatch element, it might not be possible to use them together.
It could also be a good idea to add this to the documentation.

Thanks @babu-ch, warning has gone.

For this case, maybe we can add <!-- v-if allow-mismatch --> to handle this case.
