mithril.js: vnode.dom in component with array at the top level returns the first child

Expected: vnode.dom would return a NodeList or an Array

Actual:

var component = {
     oncreate: function(vnode){
          console.log(vnode.dom)
     },
     view: function(){
          return [
               m('.first'),
               m('.second')
          ]
     }
}

This example logs out <div class="first"></div>
