on the View Message page, add the vertical divider bar between Edit and Delete

See the screenshot I will attach.

Signed in as an admin, view a message, such as:

You will see that the Edit and Delete links at the top right in the message title header bar are not shown with the standard divider bar between them. Please add it – thanks!
