I work on a system who always bug with the google font load, but i can\'t see when the font is not loaded because I have all these font in local (for Photoshop) so the font look
Rather than disabling the fonts on your side of things, why not use the font API in Chrome or Opera and have run through all the fonts that have been specified as follows?
document.fonts.ready.then(function(set) {
// Log that the fonts are loaded
console.log(set);
var t;
for(var t of set.entries()) {
console.log(t);
}
});
The FontFaceSet
will tell you if the font has been loaded or not.
