Messages in the Design System menu can be edited (though edits are not accepted)

Edit button was interactable and allowed me to attempt editing the message. However, when trying to submit edits, I got an error saying "we hit a snag". Incidentally, editing some of the messages also displays as if you are editing multiple messages at once, as shown in the attached screenshot.

Expected behaviour Either the edit button should not be available (similar to how it would look if you moused over a message sent by another user) or the hover menu should not appear at all. Philosophically, I'm not sure which is preferred in this specific context.
