It is a regression from 24.5 (and earlier).  It is also documented in
(emacs)Mode Line Mouse: "Furthermore, by clicking and dragging ‘mouse-1’
on the divider between two side-by-side mode lines, you can move the
vertical boundary to the left or right."  On the other hand there's also
window-divider-mode, which is new in 25.1 provides the full behavior
that is currently missing due to this bug; however, it is not enabled by
default.  But if the fix is safe (it seems so to me, but I'm not
familiar enough with the code to be certain), I would like it in 25.1.
(I use the Gtk+ toolkit but also have the scroll bar on the left).
