Unaligned rect when moving to (0, n)

[aroary]

Behavior:

When moving a widget to the most left position, the view show it placed a few pixels offset from the left.
If dropped, the position is properly replaced to the new location.
If moved more to the left so the mouse position is less than a few pixels more than the git box, then dropped, the box size is one less.

Expected:

When moving a widget to the most left position, the widget view appears like as if it is being moved to a not left most position.
