Key property not exist on virtual dom

[chemzqm]

I'm using react component animate to help me add animation to element(s), but I found not like what react did, preact not have key property on the dom:

As a result, the animation library fails to find the key and throw an error.

It would be nice if we can make key to be a readonly property on the virtual dom by using Object.defindeProperty

Perhaps preact should consider aligning their vdom properties with those of react.

Definitely something to consider. Preact-compat patches VNode to match React, but internally it would make little difference. Might be something I implement as part of cloneElement

I have a confirmed fix for the key property coming shortly.

@chemzqm I've released this under the beta tag: npm i -S preact@beta
