RadPanelBaritem's expander arrow should not be visible when there are no subitems. XAML Team has recently reviewed the status of this item.

Placeholder is set to " " and the SelectionOnFocus is set to CaretOnBeggining. When the Mask receives the focus, the caret is under the MouseClick position, not in beggining. After load and clicking in the center of the MaskedInput , no value can be inserted. The xaml team recently reviewed the status of this issue and won't be addressing it in future. Placeholder set to string.empty or ' ' should be considered not supported. Please consider using Mask="" (no-mask) instead.
Setting the Foreground property applies only to the BusyContent rather then the other content inside the control.
Select item, populate the control with new items and do multiple selection with shift key. The selected items are with one more.
If Hyperlink are placed in the content of the control while the IsBusy is set to true, those links are disabled.
