"Fetching Before Navigation" example does not work

[philipithomas]

Version

2.5.3

Reproduction link

#1144

Steps to reproduce

The previously closed issue #1144 was opened because the documentation is incorrect. The message from maintainers on that issue states that the method used on the "Fetching Before Navigation" example for the vue-router docs does not work: https://router.vuejs.org/en/advanced/data-fetching.html

What is expected?

this.post to be set

What is actually happening?

this.post is null (see issue #1144)

The example does work: http://jsfiddle.net/onve61xt/
But I understand this is confusing because you shouldn't see an error. See #1499
I never said the example doesn't work....

Next time, make sure to include a reproduction, please
