> This is intentional change by bug 1826408. You can set the `layout.css.font-visibility.private` pref value to `3` to restore the old behavior.

Correction: I think this preference (`layout.css.font-visibility.private`) was removed in bug 1847599, specifically here:
  https://hg.mozilla.org/mozilla-central/rev/eb06ef97c8af#l2.28

So I suspect the most-direct way to get back the old behavior here is to change `privacy.fingerprintingProtection.pbmode` to `false` (which is the preference that bug 1849903 enabled beyond Nightly in version 118).
