DOM update does not work after accessing data object in the "beforeCreate" hook

Version

3.0.0-rc.5

Reproduction link

https://jsfiddle.net/lucivaldocb/1ju7afcs/3/

Steps to reproduce

Click on the "Reverse message" button.

What is expected?

The message displayed in the browser must be inverted.

What is actually happening?

The message is not updated in the browser (in the DOM). That is, the DOM has not been updated.

---

1. The "message" property of the "data" object is updated as expected, but the DOM has not been updated.
2. When commenting on the code that accesses the property of the "data" object, everything works normally.

I know it doesn't make sense to access or modify a property of the "data" object in the "beforeCreate" hook, but I found this behavior strange.
