ContextMenu of DatePickerTextBox is not displayed

Bug explanation

I have rewritten the DatePicker Style to display a customized ContextMenu when right-clicking on the DatePickerTextBox.

In the code below, the ContextMenu that was displayed until 4.2.1 will be displayed as the default menu after updating to 4.3.0 or higher.

        <DatePicker Width="100">
            <DatePicker.Resources>
                <Style
                    x:Key="MaterialDesignDatePickerTextBox"
                    BasedOn="{StaticResource MaterialDesignDatePickerTextBox}"
                    TargetType="{x:Type DatePickerTextBox}">
                    <Setter Property="ContextMenu">
                        <Setter.Value>
                            <ContextMenu>
                                <MenuItem Header="1" />
                                <MenuItem Header="2" />
                                <MenuItem Header="3" />
                            </ContextMenu>
                        </Setter.Value>
                    </Setter>
                </Style>
            </DatePicker.Resources>
        </DatePicker>

Version

4.3.0 or higher
