After further investigation this issue is related to a know timing issue in the WPF platform which is why the issues status is being set as "Declined". More information can be found in the official social MSDN forums here:

Such issues should be ignored as they are timing issues in the WPF platform itself and are not critical for runtime. If you would like not to see them in the output after building your project you could use the following workaround:
- In your project's code behind set the DataBindingSource.Switch.Level to Critical. The next code snippet shows the described workaround:
System.Diagnostics.PresentationTraceSources.DataBindingSource.Switch.Level = System.Diagnostics.SourceLevels.Critical;

Is this really still not addressed? It might not be a problem at runtime, as you say, but while debugging, it is an absolute pain as it fills up my immediate window with dozens of these. When I want to compare previous output, its a real hassle to have to scroll 6 or 7 pages up (I have a lot of Watermark textboxes in some WPF apps)

Same thing for WPF RadAutoCompleteBox:

ItemTemplate and ItemTemplateSelector are ignored for items already of the ItemsControl's container type; Type='RadWatermarkTextBox'

I am switching to combobox for now.
