Currently, when inside of a ListBoxItemContainer Style, the footprint of the Element its a part of receives an adorner on hover.

This adorner includes a 'Style' button and a 'DataTemplate' button, which are both supposed to display a context menu of options for each.

However, in the case of being inside of a ListBoxItemContainer Style, the adorner's 'Style' button contains no function, does not expand a context menu, and displays a sliver of a pixel.

Repro Steps:

1) Create a Studio Project containing a MainPage.xaml

2) Introduce a ListBox Element to the root Grid of the Page.

3) Right-click on the ListBox Element, navigate to 'Style'->'ItemContainer'-->'Create'

4) In the Create Resource popup, pick any desired name, and save the Style in the Global Resources.
This will open the inline Style Dummy Editor.

5) Whilst inside the Style Dummy Editor, on the Stage, hover over the ListBox until an adorner is shown around the ListBoxItem.
Observe how in the top-left of the adorner, two buttons are present: one for Styles, and one for Templates.

6) Click on the 'Style' Adorner Button
Observe how no menu of options opens, and a small sliver of a couple pixels is displayed.

Expected Results: If there is no menu to display here, the 'Styles' adorner button should either be collapsed, or disabled.
Expected Results: If there is supposed to be a menu of options present under the 'Styles' adorner button, they should be displayed when clicking on the button.
