Even if you would be able to track js code like that, the js code can react to it's own sideeffects. E.g. have 8 Elements and encode the 8-bit Fingerprint as a custom style sheet that adds an animation some of the 8 elements. Then react on the animation events and rebuild the fingerprint. It's virtually impossible imo. Maybe it can even be formal proven.
