when installedFonts is enabled, same browser gives different identificator.

[temo-o]

var browserTests = [
"audio",
"availableScreenResolution",
"canvas",
"colorDepth",
"cookies",
"cpuClass",
"deviceDpi",
"doNotTrack",
"indexedDb",
//"installedFonts",
"language",
"localStorage",
"pixelRatio",
"platform",
"plugins",
"processorCores",
"screenResolution",
"sessionStorage",
"timezoneOffset",
"touchSupport",
"userAgent",
"webGl"
];

This appeard on windows 10; Chrome version: 79.0.3945.130.
This gave me different identificators when I visited almost clean php website and wordpress website. I've tried some more websites but identificator varied between the two.
