Shortcode in Email Subject Notification

Hi. I’m trying to use the shortcode %post_title% in the email subject, however it does not seem to work. However it works fine in the email body.

See a screenshot of the email here:

This is what I currently have set in the backend:

Is there a way to make the short codes work in the email subject line? Thank you.
