Describe the bug
Boa does stack overflow on Windows when constructing binary tree with depth starting from 1

example: a user could manually drag a docked window away from the main window or apps could position windows initially not right next to each other.

Obviously, there is no visible drag proxy in place when dragging not over browser windows.

To implement this onDragStart() needs to call Neo.Main.getWindowData() on all connected windows. The returning data object contains e.g. screenLeft,

This means dockerfile is broken ATM.
