That might very well be true, all that I can tell you with certainty is that after a couple of (Tag Groups) Updates ago I had to update the css (custom on my site for the plugin) due to Plugin reorganization.
Not a big deal but I also noticed that several things on the same page below where the plugin short code was placed had stopped working. Including a Contact Form 7 and a Twitter Feed. After checking the console and conducting some research I found that Tabs was not defined.
So I added that wrapper and it fixed the above issues. I assume it is a version thing but have not had the time to research anymore than above.
Hope this helps
