title: Assert that element is not actionable in Cypress
body: <p>If an element is not actionable on the page (in this case, covered by another element) and you try to click it, Cypress will show an error like this:</p>
  
  <pre><code>CypressError: Timed out retrying: cy.click() failed because this element:
  
  &lt;span&gt;...&lt;/span&gt;
  
  is being covered by another element:
  </code></pre>
  
  <p>Great! But is there any way to assert that this is the case, aka that the element cannot be clicked?</p>
  
  <p>This doesn't work:</p>
  
  <ul>
  <li><code>should.not.exist</code> - the element does exist</li>
  <li><code>should.be.disabled</code> - the element is not disabled</li>
  <li><code>should.not.be.visible</code> - the element is visible (just covered by another, transparent element)</li>
  <li>using <code>cy.on('uncaught:exception', ...)</code>, since this is not an exception</li>
  </ul>
