Duplicated requests to API without pagination parameters

[byfareska]

API Platform version(s) affected: 3.1.15, react admin 3.4.4

Description
Duplicated requests to API without pagination parameters on page load, menu usage or pagination.

How to reproduce
I've just pasted the index.js file from docs

import React from 'react';
import ReactDOM from 'react-dom';
import {
    AdminGuesser,
    hydraDataProvider,
    hydraSchemaAnalyzer,
} from '@api-platform/admin';

// Use your custom data provider or resource schema analyzer
// Hydra:
const dataProvider = hydraDataProvider({ entrypoint: 'http://localhost:63305' });
const schemaAnalyzer = hydraSchemaAnalyzer();
// OpenAPI:

const Admin = () => (
    <AdminGuesser
        dataProvider={dataProvider}
        schemaAnalyzer={schemaAnalyzer}
    />
);

ReactDOM.render(<Admin />, document.getElementById('root'));

Edit: the problem is also visible on official app skeleton https://github.com/api-platform/api-platform/tree/v3.1.14 Additional Context
You can see these requests on this video: https://streamable.com/1pfy9s

Reproduced. These requests seem to be necessary for introspection.

The problem comes from @api-platform/api-doc-parser. To introspect the parameters of a resource, the Hydra parser has to fetch the getList route:

It should be possible to use the main schema instead
