verify that subpixel accuracy of window scroll properties does not add fingerprinting risk

​As of Firefox 55, the window.pageYOffset, pageXOffset, scrollX, and scrollY properties now return data with subpixel accuracy. We think this means "half pixels on a macOS Retina or other high resolution display." We should determine if this adds any fingerprinting risks (and whether the values returned are already rounded when privacy.resistFingerprinting is set to true). See: https://bugzilla.mozilla.org/show_bug.cgi?id=1151421

To upload designs, you'll need to enable LFS and have admin enable hashed storage. More information
