We have fixed the issue described in this ticket and will include the fix in our next maintenance update. To apply this solution before the official update, request a hotfix by clicking the corresponding link for product versions you require.
Note: Hotfixes may be unavailable for beta versions and updates that are about to be released.
We added the BarItem.Size property that will be used to specify the size for the entire BarItem, and added the BarEditItem.EditWidth property that will be the replacement for the BarItem.Width property. The latter is now hidden, but not obsolete.
