Hey - anyone else notice that "extra" data is captured and displayed when doing a cut/copy and paste of data from one field to another in LEX only - does not happen in Classic.  For example, I copy an email address (jane.doe@invalid.example) in the Personal Email field and paste it into the Work email - I get "See Preferred Email field.jane.doe@invalid.example).  Should I raise a support ticket about this?

PS. only happens when doing from a non-Edit screen.  Like when you want to do an inline edit/move of the email address. The "extra" data is the Help Text associated with the copied field.
