// 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.
