computed attribute not updating after query runs, when using manual: false

[twelve17]

Given this option API reactive query:

  apollo: {
    message: {
      query,
      variables: { id: 1 },
    },
  },

And this computed property, which references the above reactive query property:

  computed: {
   messageSubstr() {
     return this.message?.text?.substr(0, 2);
   },
 },

The messageSubstr property does not seem to be called when the query is complete.

However, if manual is set to true and a result function is added to simply update the reactive property presumably as it would have been done via the automatic mode, then the computed property does get called:

      manual: true,
      result ({ data }, key) {
        this[key] = data.message;
      },

To Reproduce

I have created a minimal app in this code sandbox:

https://codesandbox.io/s/apollo-vue-computed-reactivity-8co7ec

Note that I ran into this issue in the sandbox, which required frequent manual reloading.

Alternatively, you can use this copy to run locally

1. Clone https://github.com/twelve17/avue
2. run yarn install, then npm run serve
3. Navigate to http://localhost:8080/

Tested with node v14.19.2, yarn 1.22.18.

Expected behavior

In the UI, both the apollo reactive property (message) is printed, and a contrived computed property as well (messageSubstr, which just does message.substr(0, 2)).

The messageSubStr computed property should be "He", e.g. the substring of "Hello World".

Actual Results

If manual = false, messageSubStr does not change from its initial (undefined) value.

If manual = true and a result callback is implemented, the expected behavior is achieved.

Versions
vue: 3.2.33
vue-apollo: @vue/apollo-option@4.0.0-alpha.17
@apollo/client: 3.6.6

(Note that for the sandbox version of the app, graphql 17.0.0-alpha1 is used, due to issues running older versions in the sandbox. graphql 16.5.0 is used in the github version.

I don't see the issue anymore using alpha 18 in your repro codesandbox :)
