Vue.js version

2.0-rc.1

Reproduction Link

https://jsfiddle.net/opa5v03j/

Steps to reproduce

1. Type something in field, and hit toggle. An alert will show saying "Goodbye!".
2. Hit toggle again, the field will reappear, with the same text
3. Hit toggle a third time, the field disappear

What is Expected?

2. The text should be gone. The goodbye alert came from the beforeDestroy callback, which indicates the component should be...destroyed.
3. The goodbye message should appear again, since the it should be getting destroyed, like in 1)

This fiddle in 1.0.26 works as expected https://jsfiddle.net/gaxfLqj6/

What is actually happening?

2. The text is remaining
3. The goodbye message is not showing
