This test checks that
:focus-visible is not triggered by mouse focus on
<input> elements which do not take text input, even if
appearance: none is used.
- If the user-agent does not claim to support the
:focus-visible pseudo-class then SKIP this test.
- Click each element element below to focus it.
- If the element has a red outline, then the test result is FAILURE. If the element has a green background, then the test result is SUCCESS.
