beforeRouteEnter does not set data on 2nd visit

2.4.0

Steps to reproduce

A bit hassle to do in a Bin. Minimal reproduction I can give is only this code and steps below:

beforeRouteEnter(to, from, next) {
  next(vm => vm.someData = 'data')
}

• Have a component with that nav guard code
• Load the page. (Data is set)
• Press back button then press forward (Or visit other routes and visit the problem route again)
• Page loads, data is not set.

What is expected?

someData is equal to data

What is actually happening?

someData is empty

you're probably looking for beforeRouteUpdate

@posva if following the description of it from here

For example, for a route with dynamic params /foo/:id, when we
navigate between /foo/1 and /foo/2, the same Foo component instance
will be reused

well then, no.

Any route I go to, when I get back to that one it doesn't update the data.

I tried to isolate everything already to the point only router and that component only remains.

Currently still talking about it on gitter somehow.

doing console.log() on next(vm => console.log() .... code....) and on created, and mounted

only mounted and created has the same output. they both have the same _uid and same everything. but the output from next()'s console.log is still the same.

it may be #1322

For anyone blocked by this issue, you may be able to get around it by observing $route and doing whatever updates you had planned in beforeRouteUpdate's next callback there.
