Although it's not very important to me, I have many ways to avoid it, but it looks like a bug.

This is not a bug, just a warn in DEV
because when you use multiple children template, the vue will wrap a Fragment around it.

There are two nodes in the example, one is the comment and the other is the element, and I think in this case the user wants to pass attributes to the element node, rather than remove comments or wrap them.
