docs: Disables spelling suggestions from the user's keyboard.
  This is necessary because some keyboards will replace the input text with
  spelling suggestions automatically, which changes the suggestion results.
  This results in a confusing user experience.
  
  @param disable {@code true} if spelling suggestions should be disabled, otherwise {@code false}
