SfChip Background is null

I'm trying to implement an SfChipGroup. I have it defined as follows:

<chip:SfChipGroup
   ItemsSource="{Binding SearchCriteria}"
   DisplayMemberPath="Criterion"
   ChoiceMode="Single"
   ChipType="Input"
   ChipPadding="8,8,0,0"
   ChipBackground="{StaticResource Surface3Brush}"
   ChipTextColor="{StaticResource InverseSurface}"
   HorizontalOptions="Start"
   VerticalOptions="Center" />

When I add an entry to SearchCriteria (ObservableCollection<SearchCriterion>, where SearchCriterion has a single public string Criterion {get; set;}), I get a visible chip.

As soon as I move the cursor onto the chip (to click the X button), I get an exception which I traced as follows:

SfChip.OnTouch -> ButtonBase.OnTouch ->

if(e.Action == PointerActions.Moved)
{
   if(Background != null && !IsEditorControl)
   {
      if(Background is SolidColorBrush && ((SolidColorBrush)Background).Color.Equals(Colors.Transparent)) << Null Reference Exception here!

Background.Color is null. In fact - the entire Background object is empty, as if a SolidColorBrush was instantiated without having any values set.
