When the app is in full screen OOB mode the placement of the drop down portion of the ComboBox control is incorrect.

The control should allow customizations in its filtering functionality, for example, the developers should be able let RadComboBox match "Á" when the user types "A".

When the ComboBox is non editable.

After making a selection in the control and changing the theme two times in a row an InvalidOperationException is thrown about the animation.

When IsEditable is set to true the SelectedItem is not updated if you delete the SelectedItem's text to match another existing item.
