Again: the way you arrange your input makes it look like you expect ([ to
apply to \grace ... rather than the preceding d8.  And

([...]) looks like the expectation that those constructs _nest_ in some
manner which they don't.  Written more in the manner in which it works it
would be

\new Voice { d8.([ \grace { e32( d cis d) } e16]) \appogiatura eis16 fis2 }

The results will be the same, of course.  But you are likely not doing
yourself a favor by formatting your input in a manner that matches your
sense of aesthetics better than the underlying realities: while it doesn't
make a difference to LilyPond, it may lead you to wrong conclusions.  It may
also make it harder for you to find "suitable"
input for constructs like

c( d)( e)

which you would likely then write as

c (d) (e)

which only looks more symmetric but isn't.  And does not behave well when
combined with other constructs, like you discovered.
