Mixin guard is not called when component has same guard

[nirazul]

Version

2.6.0

Reproduction link

http://jsfiddle.net/3crtn7ov/12/

Steps to reproduce

1. Trigger all available routes

What is expected?

Mixin guard: beforeRouteUpdate should be triggered.

What is actually happening?

Mixin guard is not triggered

I initially wanted to file an issue because the beforeRouteEnter guard showed this behaviour, but I wasn't able to reproduce it within a jsfiddle. I'm quite sure that the bug affects also the other guard.

After some more debugging, I think that the other problem (beforeRouteEnter) has to do with a difference in lifecycle hook call order. What I'im unable to see is, why there is a difference in the first place...

Jsfiddle hook call order (on full reload) - works:

Cmp: beforeCreate
Cmp: created
Cmp: beforeMount
Mixin: beforeCreate
Mixin: created
Mixin: beforeMount
Mixin: mounted
Cmp: mounted
Component HOOK: beforeRouteEnter
Mixin HOOK: beforeRouteEnter
Mixin: beforeUpdate
Mixin: updated

Hook call order in my app (on full reload) - fails:

Component HOOK: beforeRouteEnter
Mixin: beforeCreate
Cmp: beforeCreate
Mixin: created
Cmp: created
Mixin: beforeMount
Cmp: beforeMount
Mixin: mounted
Cmp: mounted
Mixin: beforeUpdate
Cmp: beforeUpdate
Mixin: updated
Cmp: updated

It looks like we forgot to add the merge strategy. For the moment, adding Vue.config.optionMergeStrategies.beforeRouteUpdate = Vue.config.optionMergeStrategies.beforeRouteEnter to your code should solve the issue
Are you using the latest versions on your project?

@posva I'm using vue-router 2.5.3 in my app. I will check if the problem with beforeRouteEnter persists in 2.6...

@posva
The second problem I mentioned seems to persist in vue-router@2.6, however there seems to be an improvement: Only the first time the route is loaded, the mixin hooks seems to fail being called, every navigation afterwards to this route calls both hooks.
I'm still trying to reproduce the error in a fiddle, but maybe that helps you pinpointing the problem in the meantime.

I've found the issue to my second problem. I'm opening a second report for it.
