Currently, if a Binding is attempted to be made on a Tooltip that is inside of a DataTemplate, it can result in crashing Studio.

Video attached.

Repro Steps:

1) Create a new Studio Project featuring a MainPage.xaml

2) Create a first DataStructure named 'ToolTipInfo', containing a 'ToolTipLabel' Property of type 'String', and served as a 'Single'.

3) Create a second DataStructure named 'ViewModel', containing a 'ToolTips' Data Property of type 'ToolTipInfo', and served as a Collection.

4) Create a Data Set for the 'ViewModel' Data Structure, apply it to the MainPage, and Generate Sample Data for it.

5) Introduce a ListBox to the Page, right-click on it, and create a new ListBox ItemContainer Template, saved to GlobalResources.xaml.

6) Inside of the ListBox ItemContainer Template, convert the root Border into a Grid.

7) Exit the ListBox ItemContainer Template, select it from the Stage, then set its 'ItemsSource' Property to be a Binding of type 'Context', and of Path 'ToolTips'.

8) Open the ListBox ItemContainer Template once again, and introduce a ToolTip Element under the root Grid created in Step 6).

9) Select the ToolTip Element, hover over its 'Content' Property, click on its 3-Dot Menu, and select 'Create Binding'.

Observe Studio crashing.

Expected Results: Bindings can be created on ToolTips without the application crashing.
