title: How to wait for element to be visible
body: <p>Is it possible to wait until an element is visible? </p>
  
  <p><code>cy.get('[data-test=submitIsVisible]').should('be.visible');</code> should error if the submit button is not visible. I want to wait until the submit button is visible. (the primary use case is visual testing, i.e. taking a screenshot of the page)</p>
