Bind to Style.TargetType Property

When we create a Style for CellValuePresenter that contains Triggers for specific edit templates to suppress Tooltips app wide for those editors e.g.

<Style.Triggers>             <DataTrigger Binding="{Binding Field.Settings.EditorStyle.TargetType, RelativeSource={RelativeSource Self}}" Value="{x:Type uc:CheckedComboList}"><Setter Property="ToolTipService.IsEnabled" Value="False" /></DataTrigger></Style.Triggers>

we create a memory leak because you can't bind to Style.TargetType without it creating a strong reference via a property descriptor.

Is there a way around this and still have it centralized specifically for the different types of Editors without reproducing the style portion over and over again?
