Subject: [PATCH] Remove excessive word counts

Resolves:

  - Duplicate event listeners are registered during every word count,
    increasing the number of word counts until the browser becomes
    unresponsive.
  - The word count is triggered multiple times on input due to listening
    to redundant events.
