M365 Changelog: Dynamics 365 Unified Interface - Grid columns shrink when selecting a row

MC437563 – On Monday, September 19, 2022, Microsoft received user reports that, following a recent service update, grids column width decreases when selecting a record.

Our investigation identified that the impact for this issue began Monday, September 19, 2022, 6:20 AM (1:20 AM UTC) , and determined that it was caused by an upgrade to a third-party component used by grids. This component has a different behavior for column sizing, causing your grid to not fill the available space on your page.
