Subject: bug#25853: [Reftex] Using the keyword label in a tikzpicture enviornment shows up incorrectly in reftex

When using a tikzpicture enviornment as follows
  \begin{tikzpicture}
    \matrix[]{
                      % First row
      \node[scale=1.3,label=below:(a)]
{\input{./latex/CH4/dishole_schematic}}; &
      \node[label=below:(b)~$20$~nm]
{\includegraphics[scale=0.6]{./figures/CH4/hole_gen_dis_20}}; &
      \node[label=below:(c)~$40$~nm]
{\includegraphics[scale=0.6]{./figures/CH4/hole_gen_dis_41}}; \\ % end of
row
      \node[label=below:(d)~$160$~nm]
{\includegraphics[scale=0.6]{./figures/CH4/hole_gen_dis_160}}; &
      \node[label=below:(e)~$400$~nm]
{\includegraphics[scale=0.6]{./figures/CH4/hole_gen_dis_400}}; &
      \node[label=below:(f)~$800$~nm]
{\includegraphics[scale=0.6]{./figures/CH4/hole_gen_dis_800}};\\
            };
  \end{tikzpicture}

The label keyword used to label the node is picked up by Reftex as a
valid label when the ref command is invoked. Perhaps one can avoid
scanning for a 'label' keyword within a tikzpicture environment?
