Sort Icon in Drupal Content view is in wrong direction

Which theme is this?

Is there consensus on what is correct sort arrow direction? Is there a Drupal standard? This issue needs updating with those facts.

Does anyone agree?

I think this is already an open issue. I don’t see why we need another.
