Cancel draft changes UI component doesn't show up for draft changes on owned models

Cancel draft changes action is a really useful UI component. Unfortunately, it doesn't work with any owned models such as but not limited to content blocks which arguably is the majority case.

Tested on CMS 4.13.

Thoughts on solution

The only issue with this component is the display condition otherwise the functionality is fine and will work with nested models.

$stagesDiffer = $this->stagesDiffer(); <--- change this to stagesDifferRecursive()


// "rollback"
if ($isOnDraft && $isPublished && $canEdit && $stagesDiffer) {
    $moreOptions->push(
        FormAction::create('rollback', _t(__CLASS__.'.BUTTONCANCELDRAFT', 'Cancel draft changes'))
            ->setDescription(_t(
                'SilverStripe\\CMS\\Model\\SiteTree.BUTTONCANCELDRAFTDESC',
                'Delete your draft and revert to the currently published page'
            ))
            ->addExtraClass('btn-secondary')
    );
}
