This test checks that using the Tab key to navigate focus to an element triggers :focus-visible matching.
- If the user-agent does not claim to support the
:focus-visible pseudo-class then SKIP this test.
- Use the TAB key on the keyboard to focus the element below that says "Focus me."
- 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.
Focus me.
