InputField BorderThicknessProperty name is wrong

[enisn]

I am attempting to change the border thickness on visual state Focused for the Material TextField input. This works as an inline style and even a contentview resource placed in the resourcedictionary... but if I place this in the "Styles.xaml" as key'd or unkey'd, the application crashes with the following error:

[mono-rt] [ERROR] FATAL UNHANDLED EXCEPTION: Microsoft.Maui.Controls.Xaml.XamlParseException: Position 12:37. Type converter failed: Exception has been thrown by the target of an invocation.
[mono-rt]  ---> System.Reflection.TargetInvocationException: Exception has been thrown by the target of an invocation.
[mono-rt]  ---> Microsoft.Maui.Controls.Xaml.XamlParseException: Position 76:37. The PropertyName of TextField.BorderThicknessProperty is not BorderThickness

This is the setter I am trying to use:

    <Style TargetType="material:TextField">
        <Setter Property="VisualStateManager.VisualStateGroups">
            <VisualStateGroupList x:Name="CommonStates">
                <VisualStateGroup>
                    <VisualState x:Name="Normal">
                        <VisualState.Setters>
                            <Setter Property="BorderThickness" Value="1" />
                        </VisualState.Setters>
                    </VisualState>
                    <VisualState x:Name="Focused">
                        <VisualState.Setters>
                            <Setter Property="BorderThickness" Value="2" />
                        </VisualState.Setters>
                    </VisualState>
                </VisualStateGroup>
            </VisualStateGroupList>
        </Setter>
    </Style>

Any help would be appreciated.
