Get an Attached Cell

Question

I want to dig into what this cell is doing:

It's clearly an attached cell but I can't get at it. Here's what I've tried:

Cells (pretty obviously not gonna work, but worth the try

Dynamic[
 cellsAll =
  Nest[
   Cases[
     Union[#,
      Flatten@Map[FrontEndExecute@*FrontEnd`ObjectChildren, #]
      ],
     _CellObject
     ] &,
   FrontEndExecute@FrontEnd`ObjectChildren[$FrontEnd],
   15
   ];
 Select[cellsAll,
   ParentNotebook[#] =!= $Failed &&

     FrontEndExecute@FrontEnd`AttachedCellParent[#] =!= $Failed &
   ] // Length,
 UpdateInterval -> 5,
 TrackedSymbols :> {}
 ]

Obviously I waited for a round of the i button to pop up. Still nothing.

So... is there any way to get at these? (if you didn't get it when it was created)

That drop down menu is not an AttachedCell.

Fascinating. What is it then? Is it accessible within Mathematica? – b3m2a1 Jul 27 '17 at 17:30

It is a custom control, built in native code. I am not aware of any top level entry point for it. – ihojnicki Jul 27 '17 at 17:36
Good to know, thanks. – b3m2a1 Jul 27 '17 at 17:37
Still haven't been able to figure out how one gets an attached cell without having captured it at creation time. Any hints there? – b3m2a1 Jul 27 '17 at 17:43
I do not believe that is possible. Is there a particular problem you are trying to solve? – ihojnicki Jul 27 '17 at 18:24
Nope. Pure curiosity. – b3m2a1 Jul 27 '17 at 18:26
