Widgets get the wrong width when resized in breakpoint mode

[rory-orennia]

Subject of the issue

If you resize a widget while in a smaller breakpoint, then save, then load that widget, it'll now have the wrong width.

Your environment

• version of gridstack.js - 10.2.1
• which browser/OS - Firefox + MacOS

Steps to reproduce

https://jsfiddle.net/8uyv7k9o/4/

1. click load
2. resize widget 2
3. click save
4. click load
5. item 2 resizes to the full width
6. open the console and see that the w: 4(or more) on that widget when it started as w: 2 and was shrunk.

Expected behavior

The widget should be the same size after load as it was when it was saved. I was hoping #2669 would solve this but it did not.
