html tags in @mention email notification

I'm trying to use the new feature that allows @ mentions in rich text fields, and have set up a custom notification to email users when they've been mentioned. 

I'm trying to get the contents of the rich text field containing the mention to display in the email notification. I selected the field using the 'add elements' dropdown in the 'compose email' section. How do I set up the template so that the contents of the field will be displayed in the body of the email without all the html tags?
