When using the Xaml version of our assemblies and the Material theme is set through the StyleManager, the glyph on the close button of each SearchAutoCompleteBoxItem element is not visible.

The cell highlighting doesn't work if the ItemsSourceProvider.ItemsSource is set at runtime, while the drop down is open. The filtering of the items works, but the cell content is not colored.

To work this around, make sure to set the ItemsSource before the drop down gets opened.
