 In [https://core.trac.wordpress.org/ticket/32715#comment:10 32715],
 @afercia recommended adding `role="presentation"` to the headings that
 mark navigation menu sections in the customizer. At that time, the
 accordion behavior was attached directly to the heading, and it was
 confusing to have heading semantics and button behavior on the same
 element. Following [r59224], the accordion behaviors are attached to a
 button nested inside the heading, and restoring the semantics of those
 headings is reasonable.

 I didn't do this in [r59924], because there are a number of other related
 changes that should also be made so that the heading hierarchy in the
 customizer makes sense.

 There are also additional considerations because the headings hierarchy of
 the page being customized are also present on the page.
