I see this bug with Mozilla 1.8b1/Firefox 1.0.2 and the attached testcase, but
the focus does not disappear when I focus "Dolore" first and use Shift+Tab to go
backwards.

The focus is being set to the link inside the drop down menu, but when that
happens the containing <ul> becomes display:none.
Result, the focus seems to be stuck, see also bug 285581.

So the problem is that once we've changed the focus content state we need to
reget the "next tabbable content", since the original one may have become no
longer tabbable...

I can't reproduce this in Firefox 15.
