Infinite sweep in Visual Studio?

Question

I came across this for many years and just wrote it down to VS oddity, but I'm curious if anyone has any explanations.

In my example below, I use the “drill” mouse in an exception to look at some values. I noticed that if I enter the Data section (it will almost disappear in the screenshot below, sorry), I can go down the endless chain Values->NodeKeyValueCollection->Non-Public Members->List , and then return to Values . I went through more than 30 levels in this recess, without end.

Is there something in the Exception object that happens like this, or is it a strange feature of drag and drop?

This means that the list object has an internal member that refers to itself. When you debug it, it gives you the possibility of infinite recursion.
