Comment (by azaozz):

 Confirmed. Happens for body width between 884px and 899px (as reported by
 Firebug's "Layout"). Caused by difference in calculating the body width,
 i.e. the responsive css kicks in at 883px rather than at 900px. Seems the
 15px difference is caused by the width of the scrollbar, works properly if
 there's no vertical scrollbar.

 @Sergey, this is currently a double-double switch:

 - Above 900px is sets 'folded' or 'auto'.
 - Below 900px is sets "unfolded' or 'auto'.

 The 'auto' is handled with responsive css. We could make it a normal
 three-way switch: always folded, always unfolded or auto, perhaps by
 changing the text "Collapse menu" to "Auto collapse" and the icon to...
 something else than arrow.
