A guess would be that unsetalf.mtx was originally made for use in text font
contexts, but I don't know for sure (you'll have to ask Ulrik). Taking the
xheight from rsfs10 when all the other fontdimens are the same as in cmsy10
looks like an error to me.

A quick work-around (which requires v1.914) would be

   \installfont{zptmcm7y}
      {kernoff,cmsy10,kernon,zryhax,ptmr8r,psyr,%
       \metrics\offcommand\unsetint,%
       unsetalf,%
       \metrics\oncommand\unsetint,%
       rsfs10,zrykernx,mathsy}
      {OMS}{OMS}{ztmcm}{m}{n}{}
