Resize neighbors instead of pushing them

[NicoLaval]

Describe the bug

Hi,

Default behavior when resizing a box is to push neighbors.

If I have a 12 columns grid with:

• A: x:0, y:0, h:10, w:6
• B: x:0, y:6, h:10, w:6

When I increase A width by 2, B will be push below.

Steps to Reproduce the Bug or Issue

Move vertical bar between A and B boxes in the "1 - " example.

(see deployed app here)

Expected behavior

I would like to obtain:

• A: x:0, y:0, h:10, w:8
• B: x:0, y:8, h:10, w:4 Or anything where wA + wB = 12

I think a way to do it is to handle the case in onResize or in onResizeStop. But if I have a lot of boxes, I'm not sure about performance (and code maintainability).

Any clean way to achieve this?
