Steps to Reproduce:

1. Create a new WPF application

2. In the main window constructor, add the following:

   BooleanToVisibilityConverter converter = new BooleanToVisibilityConverter();
   Visibility x = (Visibility)converter.Convert(true, null, null, null);
   

3. Set a breakpoint on one of the lines above

4. When the breakpoint is hit, hover over the (Visibility) type cast

Expected Behavior:

Quick Info is not shown (default behavior for hovering over a type while debugging).

Actual Behavior:

Quick Info shows the value of this.Visibility (default behavior for hovering over a property while debugging).
