Crossword Functional JS tests failing

Holy moly, I think I have it! The new code in ::setValue() is

        $this->executeJsOnXpath($xpath, <<<JS
if (typeof Drupal !== 'undefined') {
  var node = {{ELEMENT}};
  var original = node.blur;
  node.blur = function() {
    node.dispatchEvent(new Event("input", {bubbles:true}));
    node.dispatchEvent(new Event("change", {bubbles:true}));
    // Do not wait for the debounce, which only triggers the 'formUpdated` event
    // up to once every 0.3 seconds. In tests, no humans are typing, hence there
    // is no need to debounce.
    // @see Drupal.behaviors.formUpdated
    node.dispatchEvent(new Event("formUpdated", {bubbles:true}));
    node.blur = original;
  };
}
JS);

If I comment out node.dispatchEvent(new Event("input", {bubbles:true})); then the test pass. So I think the problem is that crossword.js doesn't expect the input to be triggered with no real input. The patch here guards against that possibility and passes locally. It also passes my basic manual tests, like using a backspace or a 0 on the keyboard.

It is such an incredible relief to have this fixed! This took hours and hours. It will be good to have green tests on the project page for the first time since October 2022! It was like 5 months of red.

Nicely done!
