When pulling a window from docking mouse is drawn off window title.

When you pull of the dock a Window that's is docked either on the left or right half of the screen. At the moment the window recovers the previous size before it was docked the mouse is not kept over the title bar of the window.

To recreate this bug:
1. Take any maximize capable window.
2. Grab it by the title bar.
3. Drag it to the far right of the window causing the preview rectangle to show up and drop the window so it docks on the right half of the screen.
4. Grab the window by the title bar again.
5. Pull it of to the center of the screen.

When you complete these steps, the window will re-size back to the normal size it had before you docked it to the half right. But the mouse will be in an odd position and not where it should be.

I expected the mouse to stick to the same position relative to that window.

If you need more detail and/or a screen capture video of the bug let me know.

Regards.
