I've run into both of these situation exactly in designs I've worked
on.  In both cases I've had to resort to floating the <h*> or <dt>
left, which has annoying side-effects.  A working display:run-in would
have helped out quite a bit here.

<dialog> is basically there to make people stop asking if they can use
<dl> for dialog.  It also helps prevent semantic over-broadening, but
it's mostly there to give an answer to a common author question.
