The List of Tabs button shows up on top of an existing tab and when no tab is open it actually covers up the New Tab button you can see on the right side at the end. Never been a problem and happened on the first opening of the updated version. EDIT: Just to add some info, the Tabs List also jumps all over the place, sometimes covering the New Tab button, sometimes in the middle of a tab randomly and sometimes even several inches to the right of an open tab, some of the time it just vanishes altogether.
Hopefully, this image helps in case this is not clear.
