Mute action doesn't dynamically update message list view in Smart folder

Given a smart folder defined by:

• All of the following are true
  • Message is Received Today
  • Tags = does not exist
  • Tags/Keywords = do not include = Muted

I observe the following expected behaviors:

• when I archive a message in this view, it disappears from the view instantly
• when I tag a message in this view, it disappears from the view instantly

I observe the following unexpected behavior:

• If I mute a message in this view, it remains in the view. If I then click away from that folder and back, it's no longer included in the view. Expected behavior: Messages should be removed from the view the moment they no longer match the search criteria, as demonstrated with the archiving and tagging examples above.
