There is no failure here, that I can see. There should never be a reason to
jump from a lower priority header to a higher priority header. In the
example given, chapters would normally be given unique documents, so the
hierarchy would be like this:-
<h1>Page Title</h1> (mimics the <title>...</title> element)
<h2>Chapter</h2>
<h3>Section 1</h3> (if required)
<h3>Section 2</h3>
If 'sub-sections' are required, then the documents should be further
sub-divided into sections, with each section having its own page instead.
This may seem like overkill, but it is the best method of maintaining a
proper, hierarchical structure.
Obviously there are exceptions to this. An example would be a W3C technical
recommendation. These are made available as a single, enormous HTML file for
those who prefer it, but such a file jumps up and down the header hierarchy
because the original, multi-page document (which did not do this) was
combined to make the large file.
