Black border around trac menu items
There is a black border around the menu items at the top (View Tickets, Browse Source, Roadmap, etc.) which looks like it shouldn't be there. FWICT this started after legacy/trac#20213 (moved) got fixed.
The CSS responsible for this border lives in https://trac.torproject.org/tor.css and is defined as follows;
#mainnav {
background: #f7f7f7 0 0;
border: 1px solid #000;
font: normal 10px verdana,'Bitstream Vera Sans',helvetica,arial,sans-serif;
margin: .66em 0 .33em;
padding: .2em 0;
}
