Vue.js version

2.0.0-rc.3

Reproduction Link

https://jsfiddle.net/ktsn/oc8g5dcm/6/

Steps to reproduce

Click "Add List" button.

What is Expected?

Both test1 and test2 components render the elements passed to $slots.

What is actually happening?

The test2 renders the elements but test1 is not.

Note that we can avoid this issue if adding cache: false option for the computed option.
