Odd indeed. I have restarted Emacs and saw the same thing. But now I
have a more clear picture. I think what is happening is in
org-html--wrap-latex-environment, there is a caption provided which are
the numbers. This only affects latex environments, and does not affect
$$ (//), etc.

If you have org-html-with-latex set to t or mathjax, you get this behavior:


#+BEGIN_SRC emacs-lisp
(org-export-string-as "\\begin{displaymath}
  \\int   f dx =0
\\end{displaymath}"
		      'html t)
#+END_SRC

#+RESULTS:
: \begin{displaymath}
:   \int   f dx =0
: \end{displaymath}

but, in org-mime this is overridden by setting that to dvipng. That
isn't what causes the numbers to appear though, at least not directly.
Somehow, this triggers a call to org-html--wrap-latex-environment where
the new caption gets inserted.

#+BEGIN_SRC emacs-lisp
(org-export-string-as "\\begin{displaymath}
  \\int   f dx =0
\\end{displaymath}"
		      'html t '(:with-latex dvipng))
#+END_SRC

#+RESULTS:
:
: <div class="equation-container">
: <span class="equation">
: <img src="ltximg/latexS2DUgE_8e5abfd22f18b9fd072a0f1273f49cd3a35040d3.png" alt="latexS2DUgE_8e5abfd22f18b9fd072a0f1273f49cd3a35040d3.png" />
: </span>
: <span class="equation-label">
: 1
: </span>
: </div>
