Latex reponsive design with breqn

Question: Does the quicklatex plugin support the breqn package for responsive design? My equations run off the page in the mobile app enviorment but look great on a PC. I want the equations to be reponsive if possible.

I have tried duplicating the results for this thread: https://tex.stackexchange.com/questions/47652/breqn-specifying-the-characters-at-which-equations-can-be-broken

I have not been able to duplicate the reponsive design using the plugin. I have included the \usepackage{breqn} in the advanced tab, but it does not seem to reflect the changes in wordpress or at quicklatex.com. Is there a way to do this? If not is there an alternative and can you provide an example.

Thanks,
Brandon
