[OS X TeX] Issue with symbol fonts

[Alan Litchfield]

Hi,

I am using the new (2017) acmart template for a paper and get an error 
as below:

(/usr/local/texlive/2016/texmf-dist/tex/latex/stix/stix.sty

! LaTeX Error: Too many symbol fonts declared.

See the LaTeX manual or LaTeX Companion for explanation.
Type  H <return>  for immediate help.
  ...

l.86 ...lFont{arrows2}       {LS1}{stixsf}   {m}{it}

It appears the issue is firmly with stix and i have tried to compile 
with LaTeX and luaLaTeX.

This is a MWE:

\documentclass[acmsmall, review=false, screen=true]{acmart}

\usepackage{algorithmic}
\usepackage[notextcomp]{stix}

% Note that the option for stix required because it clashes with
% textcomp in the class file.

\begin{document}

$\fullouterjoin$

\end{document}

How would I resolve this problem? I have seen some hashed up full outer 
join symbols using other fonts but they are pretty ugly.
