 You can determine a user's window size with CSS only. See
 https://arthuredelstein.github.io/tordemos/media-query-fingerprint.html
 for a live demo. I just tested in Tor Browser and it can still show me my
 window size with security slider on high and all scripts disabled.

 I know Tor probably knows about this given the github url but is there an
 existing ticket already or implementation taking place? I cannot find it.
