Near planned top of descent, Push for Managed Descent, donut stays level, a/c maintains almost level flight, approx - 300 fpm, THR IDLE | DES | NAV on the FMA, N1 Idle, aircraft slowing towards bottom of speed window, even to below green dot if you let it. I see this a few times a year, even after FMGS Revision 1A which overhauled vertical navigation. Hmmph.
