Boxes on edit popst screen won’t fully expand in 2.8

Something I noticed when I upgraded to 2.8 that is driving me insane. It used to be that when you moved all of the various boxes (tags, category, publish, etc) to the left column, the right column would go away and all of the boxes would fill that entire space. But now even if you move all of the boxes to the left column you have an empty column and squished boxes. Is there a fix for this?
