| <p>Test ensures that if an autoscroll starts from within an entry field, it does not propagate |
| to its non-scrollable overflow ancestors.</p> |
| <p>To test manually, start text selecting with a mouse the text within the entry field. Then |
| continue to drag the mouse out of the input field boundary.<br>Scrolling should not propagate to |
| the container overflown div due to its "overflow:hidden"</p> |
| <div id="div" class="overflow-hidden"> |
| <input id="input" type="text" value="any text here!"/> |
| <button/> |
| </div> |
| <p id="result">If the test has completed this sentence should be replaced by a success message.</p> |
