Correct clipping of 3D tikz for adjustbox?

Question

Consider the following MWE:

\usepackage{tikz}
\usetikzlibrary{calc}

\begin{document}

\loremnchars[1]{255} ...

\begin{center}
\singlespacing
\begin{adjustbox}{width=0.9\textwidth}
\def\angl{70}
\begin{tikzpicture}[
  x={({cos(\angl)*1cm},{sin(\angl)*1cm})},y={(1.0cm,0cm)},z={(0,1cm)},
  every node/.append style={
    %xslant=0.0,yslant=0.0,
    transform shape,
  },
]

  \tikzstyle{rr} = [draw,fill=gray,opacity=0.5];

%   \node[] (tt) at (33,22) {};    %L1
%   \clip (0,0) rectangle (16,27); %L2

  \begin{scope}[canvas is yx plane at z=0.0]
    \draw[rr] (0,0) rectangle (15,27);
    \node[draw,align=left,anchor=south west] at (3,3.5) {\loremnchars[6]{60} \\ \loremnchars[7]{60}};
  \end{scope}

  \begin{scope}[canvas is yx plane at z=2.0]
    \draw[rr] (0,0) rectangle (15,27);
    \node[] (tdrag) at (7,24) {};
    \begin{scope}[shift={(tdrag)},
    rotate=180,
    anchor=center,
    transform shape,
    ]
      \node[draw,align=left] {\loremnchars[2]{60} \\ \loremnchars[3]{60}};
    \end{scope}
  \end{scope}

  \begin{scope}[canvas is yx plane at z=4.0]
    \draw[rr] (0,0) rectangle (15,27);
    \node[draw,align=left,anchor=south west] at (3,5.5) {\loremnchars[8]{60} \\ \loremnchars[9]{60}};
  \end{scope}

\end{tikzpicture}
\end{adjustbox}
\captionof{figure}[short]{
A short message; \loremnchars[5]{255} ...
}
\label{fig:test}
\end{center}

\end{document}

When the lines marked %L1 and %L2 are commented, as in the MWE, I get the image in the page as expected (click for full-size):

Unfortunately, I have a bunch of nodes like %L1, laying outside the 3d scopes, which mess up the adjustbox margin calculation. So, since I need those nodes, I thought - maybe I can clip without removing those nodes. Unfortunately again, when I try doing that - by uncommenting the %L1 and %L2 lines in the MWE above - then I get a messed up clip, and the influence of the node is still visible:

So my question is - how can I clip the tikzpicture, so the node %L1 remains, and yet I still obtain the same margins & perspective as on the first screenshot?

If you are deliberate, you can use pgfinterruptboundingbox

   \begin{pgfinterruptboundingbox}
   \node[] (tt) at (33,22) {};    %L1
   \end{pgfinterruptboundingbox}

But remember that the bounding box is not adjusted to be within the page and with the coordinate you are giving to L1 (ie, (tt)), if you put any content in node (tt), it will go out of the page.

As noted by percusse, adding overlay option does the same.

\node[overlay] (tt) at (33,22) {};    %L1
