[XGrid] columns are reordered when onSelectionChange modifies some unbound datagrid data

[McFoggy]

• The issue is present in the latest release.
• I have searched the issues of this repository and believe that this is not a duplicate.

Current Behavior 😯

When onSelectionChange update some data (even unrelated to what is bound to the datagrid) then the column order is reset

See reproducer from fork of your sample XGrid example : https://codesandbox.io/s/material-demo-forked-r36ci

Expected Behavior 🤔

The selection does not change the column ordering.

Steps to Reproduce 🕹

• open https://codesandbox.io/s/material-demo-forked-r36ci
• change the order of the columns
• click on a row to select it

The columns are reordered to the default state for no reason.

I can't reproduce your issue 🤔

@dtassone You need to uncomment // setMyState(!myState);

sorry I didn't realized that I have saved the comment.
I have removed it, the error can be reproduced out of the box.

I have created a new reproduction to show that it's not an issue with the selection feature: https://codesandbox.io/s/material-demo-forked-4s6qs?file=/package.json, it seems related to the columns and reorder feature.
