Vue meta and serverCacheKey (LRU Caching)

[mattickx]

I'am seeing wrong meta data when using LRU caching and SSR.
Setting a serverCacheKey in a component's options, will cache the component server side.

Case:
Let's say we have a component A and B with both a serverCacheKey and a different vue meta title.

The following:

<template>
   <A>
      <B></B>
   </A>
</template>

Will result in:
The first load the rendered meta title will be Title B.
A second reload (cache hit) will render title A.

I know this is related to SSR Caching and not directly to Vue Meta.
Still, it would be helpful as I encountered this use case, as such others might aswel.
An example in the docs would do wonders 👍

Request:
SSR + Caching (LRU) components and keep rendering the correct metadata even on a cache hit.

I am not sure what we could do to fix this as afaik Vue doesnt emit any events when a component is re-used from cache? The docs also mention you shouldnt use component caching when child components produce side effects (which is what vue-meta does): https://ssr.vuejs.org/guide/caching.html#when-to-use-component-caching

But if anyone has an idea for a workaround we are open to suggestions ofc!

Btw, probably not what you need but client side the correct meta title will be displayed once the fix for #283 is released

i think:when vue instance lifecycle hooks were called,vue-meta power function will be called at the same time.
so if your nested component use cache,at the first time,you can get the correct metainfo.
but metainfo get [undefined] at the second time,because the cached component instance lifecycle hooks did not be called.
so many years have passed, and surprisingly few people have mentioned this problem.
