As it's a handwritten keyboard, and legacy at that, fixing the underlying issue will likely require development team effort to resolve.

      /* Request a new candidates list (if context not empty) */
      this.getCandidates(hiragana);
      
      /* And display the KMW title bar, ensuring minimum width */
      KeymanWeb.ShowHelp();
>>>   this.getElem().parentNode.previousSibling.style.minWidth='14em';

Looks like this.getElem() can return null in some circumstances (this.elemID = 'Help_Keyboard_japanese').

  this.getElem = function()
  {
    this.elem = document.getElementById(this.elemID);
    return this.elem;
  };

Have not yet determined the circumstances under which the Help_Keyboard_japanese element can be missing.
