The original patch was overwriting grading methods navigation.
All credit goes to Andrew Nicols.
$gradenode = $coursenode->add(get_string('grades'), $url, self::TYPE_SETTING, null,
'grades', new pix_icon('i/grades', ''));
// If the page type matches the grade part, then make the nav drawer grade node (incl. all sub pages) active.
- if (strpos($this->page->pagetype, 'grade-') === 0) {
+ if ($this->page->context->contextlevel < CONTEXT_MODULE && strpos($this->page->pagetype, 'grade-') === 0) {
$gradenode->make_active();
}
}
