title: Why cypress fails to identify if we give full class name
body: <p>If I am giving the full class name for example: <code>title-text-panel-container class-about-benefits &gt; ul</code> cypress fails to identify the element and throws below error 
  C<em>ypressError: Timed out retrying: Expected to find element: '.title-text-panel-container class-about-benefits > ul', but never found it</em>.
  Why cypress fails to identify if we give <code>full class name</code> in the test ? But it passes the test as we give the class name as per Test 2. </p>
  
  <p><strong>Test 1:</strong> <strong>Fails</strong></p>
  
  <pre><code>cy.get('.title-text-panel-container class-about-benefits &gt; ul').find('li').its('length').should('be.gte', 1);
  </code></pre>
  
  <p><strong>Test: 2 Passes</strong></p>
  
  <pre><code>cy.get('.title-text-panel-container &gt; ul').find('li').its('length').should('be.gte', 1);
  </code></pre>
