Actually, you've found a bug in Bobby, that is scheduled to be fixed in the
next maintenance release. The algorithm for heading nesting is that you
should not increase the header level more than one at a time, e.g., you can
go from H1 to H2 but not H1 to H3. The reverse is not true, however, you are
permitted to decrease the heading level any amount, so both H3 to H2 and H3
to H1 are ok. This second part is incorrectly implemented in the latest
release of Bobby. We apologize that this slipped through and caused
confusion. There was nothing wrong with your header outline.
