| This test checks that <code>:focus-visible</code> matches after a keyboard event, |
| even if the event handler calls preventDefault() on the event. |
| <ul id="instructions"> |
| <li>Click "Click here and press right arrow.".</li> |
| <li>Press the right arrow key.</li> |
| <li>If "Focus moves here." has a red background, then the test result is FAILURE. |
| If it has a green outline, then the test result is SUCCESS.</li> |
| </ul> |
| <br /> |
| <button id="start" tabindex="0">Click here and press right arrow.</button> |
| <button id="next" tabindex="-1">Focus moves here.</button> |
| <script> |
| start.addEventListener('keydown', (e) => { |
| e.preventDefault(); |
| next.focus(); |
| }); |

| assert_equals(getComputedStyle(next).outlineColor, "rgb(0, 128, 0)", `outlineColor for ${next.tagName}#${next.id} should be green`); |
| assert_not_equals(getComputedStyle(next).backgroundColor, "rgb(255, 0, 0)", `backgroundColor for ${next.tagName}#${next.id} should NOT be red`); |
