Font too small in Vector skin + workaround
for me in the latest version the fonts are too small using HeaderTabs and the Vector skin. Interestingly, if you use SemantiForms, the fonts are o.k. but once you just view the page, the fonts are too small.
You can change that putting the following line in a page called MediaWiki:Vector.css
#headertabs{ font-size:1em; }
