Tablet Portrait and Desktop XL article previews are cut off to the right for me (Chrome). The preview buttons look nice in the classic visual but poorly in the classic source. Can you change the current tooltips with those used for the other editing buttons?

As another note, the removal of the preview dropdown menu is causing a bug with the AdvancedOasisUI script.
