This is expected: we're now (correctly) loading the italic face of the system font, so that'll increase the footprint of the macOS font-related objects that have been instantiated. The cpstartup regression noted in bug 1806844 is essentially the same thing, and a patch to try and mitigate it is landing there, so dup'ing to that bug.
