class on v-component will override class of first node

[zhongqf]

Any classes on v-component (replace: true) will override the class of first node in template. Bug? or a desired behavior? Maybe append the classes to first node will be good. :)

The proper behavior should be the attributes on component template overwriting the placeholder.
Merging them is more complex because they need to be compiled in different scopes.
