hello based on the title of this post, I believe I have encountered the same problem.
I have Facebook and twitter icon widgets applied within the tab, on the left, but the icons are app reading just outside of the tab box.
I am literally new to WordPress and coding and trying my very best, and sorry for my lack of general know-how, but may I get some insight as to what could be the problem and what I can do to fix it.
Thanks Much!
