constructor(props) {
      super(props);

      this._manager = new HotKeysIgnoreOverrideManager(eventManagerMethod);
    }
A component that causes React Hotkeys to ignore the results of
Configuration.ignoreEventCondition and instead either force the event to be
ignored or observed. By default, this is all key events, but you can use
the only prop to provide a whitelist, or the except prop to pass a blacklist.
