It’s what I’d expect with the below modification to
NS_PARENT_WINDOW_TOP_POS, so if Emacs 25 does that too then I’m happy.
I was thinking that without the modification, Emacs 26 would do
strange things, just like it did with positioning the mouse pointer.

Thank you for working on it. Besides, I introduced this particular
bug.

Look at compute_tip_xy in nsfns.m. It moves tooltips into the positive
screen space. I’ve not managed to get to grips with this code yet.
I think what we want is for it to try to keep the tooltip on one
screen, so it’s not spanning two monitors, but allow it to go into
negative space.
Perhaps this should be a separate bug report.
