Font size bugs on the MacOS app

Thanks a lot for looking into this. While on the subject, two more things: * The web app lags a lot if the model renders a lot of math / latex. I work on math mostly, some coding stuff. The web interface is basically un-useable even with one answer that is somewhat latex (math) heavy. I can’t scroll through, copy paste things, navigate around. The Mac app is a lot better. * It would be good to have vim / vscode like tabs in the Mac app. This is mostly why I still need to use the web app. Thanks again!
