Comment (by flngerprlnt):

 Not only DOMRect readouts of HTML elements (text transformations, buttons,
 progress elements, ...)  itself are fingerprintable
 (https://privacycheck.sec.lrz.de/active/fp_gcr/fp_getclientrects.html)

 but DOMRect also makes for example

 MathML Fingerprinting
 (https://privacycheck.sec.lrz.de/active/fp_ml/fp_ml.html)
 Emoji Fingerprinting
 (https://privacycheck.sec.lrz.de/active/fp_e/fp_emoji.html)

 more effective.
