It looks like I can't repro in emacs -Q with horizontal scroll bars
enabled. I still can with my config, I don't know what the difference is.

It turns out the finger pointer shows up when my mouse is over the modeline
of the parent frame. With emacs -Q the child frame happens to overlap it.
If I move it away, I can't see the pointer anymore.

'resize-mini-windows' as nil doesn't seem to cause a vertical drag cursor
to show up on the child frame if I move it away from the parent frame.

Here's a gif of what's happening:
