mouse-follows-focus and multi-monitor setups do not work well together

[skarndev]

Description
The mouse-follows-focus feature works fine on multi-monitor setups when navigating via keyboard. However, it makes moving windows with a mouse / trackpad to another screen totally impossible and explodes the entire workspace.

From the observed behavior it looks like, as soon as the moved window is reaching another screen, Aerospace somehow registers the focus changed event and tries to move the the mouse to the center of the window. Since the window is not yet placed on the monitor, its center is likely to be on another screen, thus, moving the mouse pointer back there and disrupting the drag before you have a chance to release the window.

I was in the process of writing one, but that's the last one where I observed the issue.

# Reference: https://github.com/i3/i3/blob/next/etc/config

# i3 doesn't have "normalizations" feature that why we disable them here.
# But the feature is very helpful.

# Give normalizations a chance and enable them back.

I experience the same issue here as well and it works fine if I don't have any move-mouse in my config.

Basically, enable this and try dragging windows around multiple monitors. There's a jerk that mouse moves back and you are fighthing with it probably due to what @skarndev described
