Comment (by afercia):

 [attachment:"49288.10.diff"] adds a fix for the `max-width: 850px` media
 query, that is: when the post edit screen auto-switches to one-column
 layout under a viewport width of 850 pixels and before the responsive view
 kicks at 782 pixels.

 Note: this is an edge case because the difference between these two
 viewport widths it's a "range" of only 68 pixels. There are other cases in
 core and I ''think'' they originate from a time when the responsive view
 switch at 782 pixels wasn't implemented yet. These special cases, together
 with the admin menu "auto-fold" maybe don't make much sense any longer and
 maybe, for the future, it would be worth considering to remove them now
 that there's a responsive view.
