Columns in grouped Grid with a locked column have incorrect width

[nelito987]

Bug report

When the Grid is grouped and there is a locked column set, the grouping columns and the locked column have incorrect widths.

Reproduction of the problem

1. Open the Dojo example - https://dojo.telerik.com/@NeliK/aYUyeyAS

Current behavior

The width of the locked column is 103px although the configured width is 50px. The grouping columns have a width of 66px although the width applied from the theme is 32px.

Expected/desired behavior

The width of the locked column should be according to the value set in the configuration of the Grid. The grouping column should have a width as applied by the themes.

The issue is a regression starting with R2 2023 SP1 (version 2023.2.718) release.
