      Description

      The display macro contains code that should prevent a recursive infinite loop, but that check is not currently working and instead the user experiences a StackOverflow error.

      Steps to reproduce:
      1. Create a page with the path "Main.Display1.WebHome" with the following content:

      display 1

      {{display reference="Main.Display2.WebHome" /}}
      

      2. Create a page with the path "Main.Display2.WebHome" with the following content:

      display 2

      {{display reference="Main.Display1.WebHome" /}}
      

      Expected:
      A red box on the page with the macro exception "MacroExecutionException: Found recursive inclusion of document"

      Actual:
      A red box on the page with the generic exception "StackOverflowException: stack too deep"
