Hi guys,
When ribbon is minized and shading is applied to a table cell, the ribbon would throw a NullReferenceException an crash. The problem happens within BarItemLink.Enabled when EnabledLinkCore is true and this.Item is null.
To repro run the attached project (RichTextEdit + Ribbon), insert a grid, position caret in a cell. The Design tab will appear, go to Design tab, click Shading dropdown (so the colors appear), pick any color -> booom crash.
