This test checks that :focus-visible always matches on <input> elements which take text input, regardless of focus mechanism.
  
    - If the user-agent does not claim to support the 
:focus-visible pseudo-class then SKIP this test. 
    - Click each form element below to focus it.
 
    - If the element has a red background, then the test result is FAILURE. If the element has a green outline, then the test result is SUCCESS.
