[Bug][Grid] column width is not set properly in StrictMode

[filipKovachev]

When setting the App in StrictMode, the columns do not span entirely.

This can be seen in the following example:

https://codesandbox.io/s/kendo-grid-col-width-forked-n3wrkn?file=/src/index.js

Steps to reproduce:

1. Open the example and observe the empty space to the right.
2. Remove StrictMode and notice that the Grid columns are then positioned as expected.
