gnome-shell: disable "snap maximize"?

[Miles Bader <miles@gnu.org>]

Hi, another question about gnome3 / gnome-shell:

When one is dragging a window, if you happen to drag into the top-bar
area of the screen, it _maximizes_ the window... this is very
undesirable, as it's very easy to do this by mistake if you want to
position the window as far upwards as possible.

Is there a way to turn this behavior off?

[This time I looked for likely settings in the output of "gsettings",
but didn't see anything...]

Thanks,

-miles
