[3.0-beta] MockedProvider: addTypename does not work with @client

[timonkbd]

Intended outcome:

The following query should match with the provided mock when testing a component that queries the local state using the @client directive:

query GetLocalState {
  paletteType @client
}

const mocks = [
  {
    request: { query: GetLocalStateQuery },
    result: { data: { paletteType: 'dark' } },
  },
];

const resolvers = {};

const wrapper = mount(
  <MockedProvider mocks={mocks} resolvers={resolvers} addTypename={false}>
    <ComponentWithLocalState />
  </MockedProvider>
);

Actual outcome:

I had no problems using the approach above with apollo-client@2.6.8, but after the migration to @apollo/client@3.0-beta the mock only matches the query when removing @client or adding the __typename field. So I guess it has something to do with the addTypename prop.

query GetLocalState {
  paletteType
}

query GetLocalState {
  __typename
  paletteType @client
}

How to reproduce the issue:

I think the above explanation should make the problem clear and reproducible. If I find time (and if needed), I can also try to set up a repository to reproduce the problem.

This should no longer be an issue in @apollo/client@latest - let us know otherwise, thanks!
