paths:
  /projects:
    get:
      $ref: '#/components/schemas/ProjectsQuery'
    post:
      $ref: '#/components/schemas/ProjectsQuery'


components:
  schemas:
    ProjectsQuery:
      summary: Get a list of projects
      tags:
        - projects
      parameters:
        - name: limit
          description: number of projects
          schema:

Swagger-UI configuration options:

// Library to read yaml files
const yaml = require('yamljs');
// Import the swagger logic
const swaggerUI = require('swagger-ui-express');
// Read the specification
const specification = yaml.load(`${__dirname}/description.yml`);
// Set some swagger configuration parameters
const swaggerConfig = {
    customCss: `.swagger-ui .topbar { display: none }`,
    customSiteTitle: `Minimal example`,
    swaggerOptions: {
        supportedSubmitMethods: [] // Disable all 'Try it out' buttons
    }
};
// Parse it with the Swagger logic
const swaggerSpec = swaggerUI.setup(specification, swaggerConfig);
module.exports = swaggerSpec;

Describe the bug you're encountering

When using $ref to define a path the swagger display is buggy.
It is ignoring the summary and the tags (at least) until we click on the endpoint.
Once clicked, it starts to work perfectly.

To reproduce...

Steps to reproduce the behavior:

1. Just open it
2. Click on the endpoint to fix de bug until we reload the page

Expected behavior

Works properly from the beginning

Screenshots

Before:

After:

Start with the provided description.yml and the shown swagger-ui-express setup, then load the OpenAPI 3.0.2 example in Swagger UI 4.1.2 or 5.0.1. Compare the initial rendering with the state after clicking an endpoint; done means the referenced path shows its summary and tags correctly before any click.
