Disable header and footer in latex previews

Question

When I write latex to be included in org mode it includes the header styling which is to be applied to the pdf export only. This makes it difficult to use org mode with latex previews. Is there any way to remove the header styling and restore the normal latex previews?

In this picture for instance, there is more content below the latex preview that is not being shown.

* Electric Charge
Charge is the fundamental property of matter that exhibit 
electrostatic attraction or repulsion in the presence of other 
matter. The charges of free-standing particles are integer 
multiples of the elementary charge $e$; because of this we say 
that electric charge is quantized.

My config has latex previews turned on but when I include the setup file, the latex preview adds the headers which expand the latex preview to take a very large amount of space.

The relevant parts of the setup file (tutoring.org) are as follows:

#+LaTeX_CLASS: org-plain-latex
#+LaTeX_CLASS_OPTIONS: [letterpaper, 11pt]
#+LATEX_HEADER: \usepackage{titling}
#+LATEX_HEADER: \setlength{\droptitle}{-6em}
#+LATEX_HEADER: \usepackage[top=1in, bottom=1.25in, left=1.55in, right=1.55in]{geometry}
#+LATEX_HEADER: \usepackage{fancyhdr}
#+LATEX_HEADER: \pagestyle{fancyplain}
#+LATEX_HEADER: \headheight 35pt
#+LATEX_HEADER: \lhead{\Subject\\\Unit}
#+LATEX_HEADER: \chead{\textbf{\Large \classnumber}}
#+LATEX_HEADER: \rhead{\Author \\ \today}
#+LATEX_HEADER: \lfoot{}
#+LATEX_HEADER: \cfoot{}
#+LATEX_HEADER: \rfoot{\small\thepage}
#+LATEX_HEADER: \headsep 1.5em

#+LATEX_HEADER: \usepackage{hyperref}

My config defines the org-plain-latex style:

(with-eval-after-load 'ox-latex
  (add-to-list 'org-latex-classes
               '("org-plain-latex"
                 "\\documentclass{article}
           [NO-DEFAULT-PACKAGES]
           [PACKAGES]
           [EXTRA]"
                 ("\\section{%s}" . "\\section*{%s}")
                 ("\\subsection{%s}" . "\\subsection*{%s}")
                 ("\\subsubsection{%s}" . "\\subsubsection*{%s}")
                 ("\\paragraph{%s}" . "\\paragraph*{%s}")
                 ("\\subparagraph{%s}" . "\\subparagraph*{%s}"))))

Issue still remains when running emacs-q
