TextPosition label sizing is incorrect. Regardless of AutoSize and AutoSizeLabels settings, only the first label size is calculated correctly. I've attached a project and a screenshot of the issue. It seems size isn't calculated if TextPosition == Telerik.WinControls.UI.LayoutItemTextPosition.Top.

Consider the Salary field in the Employee class. A common requirement would be to change the default spin editor with a RadMaskedEditBox in the EditorInitializing event. However, if you follow the steps described here: https://docs.telerik.com/devtools/winforms/controls/datalayout/change-the-editor-to-a-bound-raddropdownlist

the BindingCreating event wouldn't be fired for any editor that is not some of the default ones.
