This is a CSS issue, not an HTML one - floated elements don't affect
the sizes of their container elements, so if you float out all the
contents, it collapses to a 0-height element (and, for inlines,
0-width).

The semantics are still fine.  You can avoid any weirdness with focus
outlines by floating the <a> instead - it should have the same effect.
