Comment (by celloexpressions):

 To avoid keyboard accessibility issues when sections are opened
 programatically, we need to move the tabindex and focusing parts of this
 code from section - attachEvents() into onChangeExpanded:
 {{{
 if ( section.expanded() ) {
         section.collapse();
         backBtn.attr( 'tabindex', '-1' );
         sectionTitle.attr( 'tabindex', '0' );
         sectionTitle.focus();
 } else {
         section.expand();
         sectionTitle.attr( 'tabindex', '-1' );
         backBtn.attr( 'tabindex', '0' );
         backBtn.focus();
 }
 }}}

 Currently can be seen in Menu Customizer when adding a new menu.
