This problem happens if a widget is with **data-gs-auto-position="yes" ** and grid's option 'float' is true.

To reproduce it :
test_jump.zip

1. first try to drag the widget far away of its parent grid limits (top,right or left)
2. then try to resize it far beyond its parent grid limits.
3. at the end of the resizing, the widget will 'jump' down automatically.
   (In most case, it works at first try :))

With height option defined :
Moreover, if the grid's parent has a height option defined the widget will ignore it and jump below!
You can drag it back to the parents grid limits, but sometimes it seems that the widget is 'corrupted' and has strange behaviours when resizing/moving;
