I think this should work, but I believe the latex
files that is used to create the image does not have te right
usepackage statement.

Right now I am on a machine without dvipng, so I cannot try this:

1. pull from git
2. Instead of #+LaTeX_HEADER: \usepackage{tikz}, use

   (setq org-export-latex-packages-alist '(("" "tikz))

   because this customization will now also be seen by
   the preview process.

I hope that then the preview will also work.
