c# - 为什么此工具提示仍然启用？

Question

我正在开发一个 WPF 应用程序，我正在尝试有条件地启用工具提示。这很奇怪，我意识到即使我明确地将工具提示设置为不启用(ToolTipService.IsEnabled="False")，工具提示仍然会显示。谁能弄清楚这里发生了什么事吗？

 <TextBlock Grid.Row="2"
    Grid.Column="0"
    VerticalAlignment="Center"
    FontSize="15"
    ToolTipService.IsEnabled="False"
    Visibility="{Binding IsConnected, Converter={StaticResource BooleanToVisibilityConverter}}">
    <fa:ImageAwesome Icon="{Binding Path=BatteryLevelIcon, UpdateSourceTrigger=PropertyChanged}"
       Height="20"
       Width="20"
       Foreground="Green"
       Visibility="{Binding IsConnected, Converter={StaticResource BooleanToVisibilityConverter}}" />
    <ToolTipService.ToolTip>
       <TextBlock>
          <TextBlock.Text>
             <MultiBinding StringFormat="{}{0}%">
                <Binding Path="BatteryPercentage" />
             </MultiBinding>
          </TextBlock.Text>
       </TextBlock>
    </ToolTipService.ToolTip>
 </TextBlock>
