Comment (by mikeperry):

 Apparently this may also be an issue if the user tweaks some Windows DPI
 scaling option? Unclear what that is or what that means.

 I'm less concerned about zoom being detectable, especially since the
 process of zooming will cause all sorts of CSS reflows that will likely be
 detectable no matter what, at least with how zoom is currently
 implemented.

 There's also #4316 though, which is perhaps more concerning. I wonder if
 #4316 is still even an issue though. That sure is an old ticket.
