| 6 | <p>To manually run this test, please follow the steps below:<br/> |
| 7 | 1. Place caret at the end of 'hel<i>lo wo</i><b>rld</b>'.<br/> |
| 8 | 2. Press Ctrl-Backspace (Alt-Backspace on macOS) to delete word backwards.<br/> |
| 9 | 3. Place caret at the end of 'test2' => Press 'a' key.<br/> |
| 10 | 4. Select 'test2a' => Press 'b' key.<br/> |
| 11 | 5. Select 'b' => Bold text through context menu or Command-b on macOS.<br/> |
| 12 | 6. Place caret at the end of 'test3' => Press 'a' key => Press Backspace key.<br/> |
| 13 | <br/> |
| 14 | If a "PASS" result appears the test passes, otherwise it fails</p> |
