| <p>This test ensures selectstart event fires when selection is created by arrow key and script can prevent the selection change.</p> |
| If running this test manually, click on the div ("Hello World") and try to select the text using arrow keys.<br> |
| Expected result: SelectStart event will fire when user starts extending the selection, but due to script preventDefault it prevents the selection change.<br> |
| <div contenteditable>Hello World</div> |
