| <p>The test starts automatically. New instances are continuously created until an error is detected.</p> | |
| <p>Iteration Count: <span id="iteration">0</span> ...</p> | |
| <p>In Edge 40.15025.1000.0, this works fine until you open the dev tools. Then, the error is triggered after several | |
| seconds (~5s) and our alert dialog is show.</p> | |
| <p>If the dev tools are already open when the page is loaded, the error is not triggered until you close and re-open | |
| them.</p> | |
