WordCloud does not work with drilldown

Actual behaviour

The Wordcloud series does not work with drilldown. After drilling up with breadcrumbs, the parent series is not displayed as it initially was (specifically - the yAxis labels are missing).

Hi!
I have prepared a workaround for that issue. You can check it in the demo below. If you want to use it in your project now, just copy-paste the IIFE function with the plugin.

A similar solution will be used in the Wordcloud series code.
