This sounds like a bug.  If you feel confident enough, try changing
the @Protect symbol (line 424 of $(LOUTLIB)/include/dsf in my version)
so that it grabs more space e.g. change the current definition from

    def @Protect right x { 3.0f @High //0io // x }

to

    def @Protect right x { 3.5f @High //0io // x }

and let me know how it goes.  I can see that the current 3.0f probably
only grabs enough space to guarantee that the heading, the gap below
it, and one line of the first paragraph fits, and that unbreakablefirst
might then disallow that one first line, giving the problem you had -
but it needs experimentation to be sure.

Alternatively, make a small test file that elicits the problem and
send it over to me.
