Prompt Title: Input handler not working.

Sure, you can modify the code to loop through all the shadow roots on the page and add the observer to each one. Here's the updated code snippet that should achieve what you're looking for:

javascriptCopy code
// Set up the mutation observer
const observer = new MutationObserver(function(mutationsList, observer) {
  // Loop through all the mutations
  for (const mutation of mutationsList) {
    // Check if any nodes were added to the DOM
    if (mutation.type === 'childList' && mutation.addedNodes.length) {
      // Loop through all the added nodes
      for (const addedNode of mutation.addedNodes) {
        // Check if the added node is an input element with an empty value
        if (addedNode instanceof HTMLInputElement && addedNode.value.trim() === '') {
          console.log('Found input with empty value:', addedNode);
          // Do whatever you want to do when an empty input is found
        }
      }
    }
  }
});

// Set up the observer settings
const observerSettings = {
  childList: true,
  subtree: true,
};

// Loop through all the shadow roots and observe them
findShadowRoots(document).forEach(function (shadowRoot) {
  observer.observe(shadowRoot, observerSettings);
});

function findShadowRoots(root) {
  let roots = [];
  if (root.shadowRoot) {
    roots.push(root.shadowRoot);
  }
  root.querySelectorAll('*').forEach(function (element) {
    if (element.shadowRoot) {
      roots.push(element.shadowRoot);
    }
  });
  return roots;
}

In this code, we first define the observer and observerSettings objects as before. We then use the findShadowRoots function to find all the shadow roots on the page and add the observer to each one using a forEach loop.

Inside the observer callback, we loop through all the mutations and check if any nodes were added to the DOM. If so, we loop through all the added nodes and check if each one is an HTMLInputElement with an empty value. If we find one, we log a message to the console and perform any other actions you want to do when an empty input is found.

Note that this approach will not detect changes to existing input elements that become empty, only new input elements that are added to the DOM with an empty value. If you want to detect changes to existing input elements as well, you'll need to add additional event listeners to those elements.
