No, in this case, they're just handling the non-conformant content in
the most sane way, which I believe (in this case) is correct handling
according to traditional SGML rules.
See the Parse Tree produced by the validator for that construct
(ignore the 2 expected validation errors):

According to the formal content model, yes, but when a browser
encounters a real world document has that construct, what do you think
the browser should do with it?

The A element is just defined as a hyperlink. Whether or not it's a
section is irrelevant.

But that isn't backwards compatible.
