Window can get maximized on the wrong monitor with a dual monitor setup, when more than half of it is on the second monitor

[Dan]

Reproducible: always

Requirements:
 - Dual monitor setup

Steps to reproduce:
1. Open any window
2. Position more than half of it on one monitor (Will call this one Monitor1), while the rest is on the second monitor (Will call this one Monitor2).
3. Now, snap the window to the top bar of Monitor2.
4. Before releasing the mouse click, an "maximizing" animation will show on Monitor2.
5. When mouse button is released, the window is maximized on Monitor1.

Expectation:
Since the animation is shown on Monitor2, I would expect the window to get maximized on Monitor2.

My opinion is that it was probably made like so by design, so when clicking the maximize button, the window gets maximized on the monitor where the majority of it resides. But it is confusing to show the maximize animation on one screen and maximize it on another.
