DatePicker DPI Awareness Issue

Hello,

I'm using the lib in a WPF app with PerMonitorV2 DPI awareness enabled. Things all seem fine, until I use the DatePicker control.

The popup appears blurry and has not been scaled properly. The textbox on the main page displays fine.

I have two DatePickers. I've set the first one to use the standard WPF style, and the second one to use the material style. The standard one is fine, the material style is not.

My code is:

`
<Grid.ColumnDefinitions>




</Grid.ColumnDefinitions>

                    <TextBlock Grid.Column="0" Text="From:" VerticalAlignment="Center" Margin="0 5 5 6" />
                    <DatePicker Style="{x:Null}" Grid.Column="1" Width="85" FirstDayOfWeek="Monday" IsTodayHighlighted="False" SelectedDate="{Binding FilterStartDate}" DisplayDateStart="{Binding DatePickerMin}" DisplayDateEnd="{Binding DatePickerMax}" />

                    <TextBlock Grid.Column="2" Text="To:" VerticalAlignment="Center" Margin="8 5 5 6"  />
                    <DatePicker Grid.Column="3" Width="85" FirstDayOfWeek="Monday" IsTodayHighlighted="False" SelectedDate="{Binding FilterFinishDate}" DisplayDateStart="{Binding DatePickerMin}" DisplayDateEnd="{Binding DatePickerMax}" />
                </Grid>`

Without the popups open:

WPF Style:

Material Style:

Please forgive me, I don't know if this is something I've done, or is a bug in the theme!

Thanks

从提供的 WPF XAML 复现程序开始，并比较 PerMonitorV2 DPI awareness 下标准 DatePicker 弹出窗口和 material 样式弹出窗口的行为。完成的标准是 material 样式弹出窗口能够正确缩放且不再模糊；该 issue 没有指定源文件或要运行的测试。
