| // Note: |
| // The order of these tests shouldn't be changed because we don't unload |
| // the external script file even if we expect the <script> element will be |
| // removed by childNode.remove() and Garbage Collection after a test has been |
| // finished. Therefore, I intentionally make them load externalScript1 and |
| // externalScript2 alternately, and we can check if the results are changed |
| // after reloading the other script. |
| // Throughout this test, we periodically need to verify that a script |
| // *does not load* after we've made a tweak. To do that, we have to |
| // wait "long enough for it to have loaded", and then make sure nothing |
| // has changed. We estimate "long enough" by adding an extra dummy |
| // <script> element and watching for its load event. |
