no issue
- when viewing the email preview in the post preview modal having your email address pre-filled makes sending yourself an email preview much quicker as there's no need to type anything

- fixed incorrect tracked variable name for the email preview address
- fixed incorrect access of `this.post` instead of `this.args.post`
- re-throw any error that is encountered so the cause is not silently lost
