I circumvented it with this one-liner (credit to DSV4 0731, who kindly read the minified scripts for me). I got it to work by injecting it at the console after a refresh, and before the scripts finished loading (there's probably more robust ways but I'm lazy and this does work). FontFace.prototype.load = function() { return Promise.resolve(this); }; Anyway; those are my two cents.
