This feature has been broken in brave, and because of that it was disabled before with a build flag. In M149 that build flag doesn't produce a coherent build anymore, so we fall back to overriding the feature flag.

Ink2Manager keeps track of the IDs previously sent and will not repeatedly send the same font data to the backend to load, and it will tell the getTextInfo() private API not to serialize the known fonts. The backend is expected to save and reuse the font data from the frontend.
