        Title="设置" Height="600" Width="800" >
    <ui:NavigationView x:Name="nvSample5" Header="设置" IsTabStop="False" PaneDisplayMode="Auto">
        <ui:NavigationView.MenuItems>
            <ui:NavigationViewItem Content="Menu Item1" Tag="LockTimeAboutPage">
            <ui:NavigationViewItem.Icon>
                <ui:FontIcon FontFamily="Segoe Fluent Icons" Glyph="&#xe946;" />
            </ui:NavigationViewItem.Icon>
        </ui:NavigationViewItem>
       </ui:NavigationView.MenuItems>
             <ui:Frame x:Name="contentFrame5" Margin="0,0,0,0" />
    </ui:NavigationView>

Additional Notes

Validations

• Check that there isn't already an issue that reports the same or similar problem.
• Check that this is a bug in the library that should be fixed, not a feature, also this is not about the documentation. (Or please choose the right repo and template.)
• This is one single problem, or a few problems with the same cause. (If you want to report multiple problems, please create one issue for every single problem.)
• You've checked that this problem still exists in the latest version. (Keep in mind that we don't provide any support for old versions.)
• You know that we can't guarantee that we will satisfy your request. This is not really our duty to do everything anyone asks for. Also, you will treat our staff, contributors, and other users with respect and kindness.
• You're sure there's something wrong with the library itself, not how you're using it. (If you are having issues using it and need help, please go to discussion.)

这个问题很久以前就有了，目前可以通过手动设置 IsPaneOpen 为 false 来修补这个问题。我过几天看能不能修一下代码。
