 The {@link module:word-count/wordcount~WordCount} plugin provides:
-  * {@link module:word-count/wordcount~WordCount#wordCountContainer} method. It returns a self-updating HTML element which is updated with the current number of words and characters in the editor. There is a possibility to remove "Words" or "Characters" counters with proper configuration of {@link module:word-count/wordcount~WordCountConfig#displayWords} and {@link module:word-count/wordcount~WordCountConfig#displayCharacters},
