Minimal pure PostScript file of box with title

Version gs 9.27 appears to have introduced a new BoundingBox error. The minimal PostScript file bug.ps (attached) draws a box with a title.  DEVICE=bbox yields a bounding box that clips most of the title.

In 9.26 we get this correct result:
gs -q -dSAFER -dNOPAUSE -dBATCH -sDEVICE=bbox bug.ps
%%BoundingBox: 71 71 361 385
%%HiResBoundingBox: 71.278803 71.278803 360.721184 384.173988

In 9.27 we instead get this result:
gs -q -dSAFER -dNOPAUSE -dBATCH -sDEVICE=bbox bug.ps
%%BoundingBox: 71 71 361 377
%%HiResBoundingBox: 71.278803 71.278803 360.721184 376.541989

As you can see, the ymax value is too small and clipping of the title occurs.
