Being  an editor  and being  on REVIEW  are mutually  conflicting states.
Since a message cannot be half approved and half rejected, one has to win
over the other, and in 14.3 this was changed so that the editor wins. You
can make a rationale for either to win over the other. Mine is that:

- A list header option, which can only  be set explicitly and by the list
  owner,  is closer  to  the  human decision  maker  than a  subscription
  option, which is usually set via "Default-Options=" nowadays.

- A list where every  editor is on REVIEW would have  a problem if REVIEW
  were to win over "Editor=".
