Forum Navbar problem after 1.20p2 update
 

We have the following problem after upgrading from 1.19 to 1.20p2 - zzzzzz.png
As you can see, the submenus of selected tab are way too high (300px +) and they are pushed down for no reason. I can't find any margin or height property for this in stylevars. Navbar template is same as default so I have no idea where the problem is.
