 Subject: Fonts fingerprinting mitigation

+The patch disables the use of non-standard fonts by blink,
+used for device fingerprinting.
+Access to local fonts and downloading fonts via Android
+Downloadable Fonts API is disabled.
+In windows, the patch exposes only fonts from the default
+installation based on the user language exposed to the websites,
+eliminating the ability to retrieve fonts handled differently
+by gdi and directwrite.
+It is possible to restore the original behavior via the
+fonts-fingerprint-mitigation flag, which is active by default.
