fix: [data grid] Entering in edit mode, reload column configuration #12429

[GeoffreyHervet]

As exposed in #12429, their is an issue during rerendering columns : the user column position was reset and also the columns size.

It looks I have some issue with the unit tests, If someone wants to help me, feel free :)

I hope it will satisfy you and will merge soon. Don't hesitate if you have any remarks.
