>+        FontDescriptionKey::computeHash requires implicit instantiation of the FontTaggedSettings template. Since the
>+        function is implemented directly in the header, this instantiation may happen before FontTaggedSettings::hash() is
>+        actually specialized in FontFeatureSettings.cpp or FontVariationSettings.cpp. To avoid compiler errors, the
>+        implementation is moved into FontCache.cpp.
>+
>+        No new tests, behavior unchanged.
