Context link is not capturing reactive var changes

[sergio-bravo]

I created a language link:

const languageLink = setContext((request, previousContext) => ({
  ...previousContext,
  headers: {
    ...previousContext.headers,
    "Accept-Language": getLanguage(),
  },
}));

export const getLanguage = (defaultLanguage?: string): string => {
  return languageVar() || defaultLanguage || "en";
};

It basically works and I can see the header is added to the request.

Problem: I expect cached queries to update automatically because the context has changed, but the new queries do not fire.

Addressed by #7350 - thanks!

I suspect this issue may not have been fixed, as suggested in #7350 (comment)

I have created a reproduction repo at https://github.com/codazzo/apollo-client-reactive-context-repro
What do you think @hwillson? I might be missing something.
