toBlocks()->toHtml() not rendering kirbytags?

I’m having an issue where my kirbytags aren’t rendering in the template via echo $page->article()->toBlocks()->toHtml();

I’ve tested by implementing a hook:

'hooks' => [
        'kirbytags:after' => function ($text, array $data = [], array $options = []) {
          var_dump("TAG!"); die;

The panel itself is triggering this hook, but the frontend just returns the plain text without processing the tags or the hook. I am on Kirby 3.6.0.
