It was my mistake. I had xaml:
这是我的错误。我有xaml：
<ContentControl>
<ScrollViewer name="viewport"/>
</ContentControl>
and "viewport.Content" was set to my UserControl from code-behind.
并且“viewport.Content”从代码隐藏设置为我的 UserControl。
It was a ContentControl who draw the focus border. I removed it and left only a . Problem solved.
它是一个绘制焦点边框的 ContentControl。我删除了它，只留下了一个 . 问题解决了。

Try it for an control set Focusable = "False". Example:
试试它的控制集Focusable = "False"。例子：
<Grid Focusable="False">
...
</Grid>
Or set the Styleto focus yourself:
或者将 设置Style为专注于自己：
<Grid FocusVisualStyle="{x:Null}" />
Also, the Styleof focus might be:
此外，Style重点可能是：
<Style x:Key="MyItemFocusVisual" TargetType="{x:Type Control}">
<Setter Property="Control.Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type Control}">
<Border SnapsToDevicePixels="True" CornerRadius="0" BorderThickness="5" BorderBrush="#7B2F81" />
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
Using:
使用：
<Grid Focusable="True" FocusVisualStyle="{StaticResource MyItemFocusVisual}" ... />

If you just want to keep it from accepting focus via Tabbing just declare it on the object via IsTabStop="False"or you can edit the control Template for it and get rid of the Focus changes.
如果您只是想让它不通过 Tabbing 接受焦点，只需在对象上声明它，IsTabStop="False"或者您可以编辑它的控件模板并摆脱焦点更改。
