Are you sure this has changed "recently"?  If you have
'temp-buffer-resize-mode' enabled, the maximum height is specified by
the option 'temp-buffer-max-height'.  With 'temp-buffer-resize-mode'
disabled there is no such bound but I see no recent change in behavior
either.

Try with 'temp-buffer-resize-mode' enabled.  If you think that the
customization used there helps, we could try to implement something
similar when that mode is not enabled.
