Nvm I fixed it. Their browser does some really quirky stuff to my styles, so I guess I'll have to reimplement my theme switcher.
i feel this.. if this is helpful, i use this bit of javascript to detect the "browser" to add my styling workarounds lol:
const isScreenshooter = /PhantomJS/.test(window.navigator.userAgent) || !!window._phantom || !!window.callPhantom;
