VueX getter caching in combination with VueX-ORM

[SimonDatapas]

Additional context

I'm not totally sure wether I'm posting this in the right repo, but I thought it might be usefull for everyone here to know.

Describe the bug / Expected behaviour

It seems that when querying VueX-ORM models inside a VueX store getter, the getter can't cache the result properly.
I have a store getter that contains a query that can take up to a full second to return the requested data (yes, lots of data).
When I call this getter twice from inside a component, the render time needed will be 2 seconds instead of 1.
If I would refactor this getter to be a state property and be updated everytime the corresponding repo's would be updated, The render time will be reduced to an instant and the time to mutate the repo's will take 1 second longer.
I would expect in my first scenario that the render time wouldn't increase no matter how many times the getter would be called from within that component. (For as far as I understand, this behaviour would be the same as store getter caching where getters only refer to store state.)

Steps to reproduce the bug

// Template inside component
<template>
   <section v-for="post in posts">{{post.name}}</section>
   <section v-for="post in posts">{{post.name}}</section>
</template>

// Computed property inside component
posts() {
    return this.$store.getters.posts;
}

// Store
getters: {
    posts() {
        return store.$repo(Post).all();
    }
}
