Thank you @a.dmitriiev for the fix. The preview loop is working fine now, but for the validation error messages, they are still showing after closing the edit form.

Steps to reproduce:

1. Enable automatic preview
2. Edit Headline paragraph
3. Remove all characters from Headline field
4. Close edit form
5. Go to config page
6. The validation error message is shown there

#35 also works, thank you!

Event listeners have been modified. Now this is using formUpdated, autocompleteclose and onDrop.

This issue needs some work:

1. Remove external debounce library and use Drupal one
2. Change some event listeners and add more suitable ones
3. Determine if current enable/disable automatic preview workflow is the best one
