Page crash when plugin is included

Error message from dist:

Uncaught (in promise) TypeError: can't access property "parentNode", f is null

Solution: if(f === null) break;

Missing case when "currentParent" is null, cannot be just else statement, throws Error because null don't have parent in DOM :)

while (!rootFound) {
      var parentType = type(currentParent)

      // We've reached the document, which means there's no shadow DOM in use.
      if (parentType === '[object HTMLDocument]') {
        rootFound = true

      // We're using a shadow DOM.
      } else if (parentType === '[object ShadowRoot]') {
        rootFound = true
        shadowDom = currentParent
        customElement = currentParent.host

      // Focus up the chain to the next parent and keep iterating.
      } else {
        currentParent = currentParent.parentNode
      }
   }
