Accidental repeated with ottava

[Knute Snortum]

I have run into something in LilyPond that's annoying -- it probably
doesn't rise to the level of bug.  When you have two notes in
different octaves but "on the same level" because of an ottava, the
accidental is repeated.  This makes sense logically because they are
not the same note, but it doesn't look right to me, at least.  Maybe
it's the intended behavior?

\version "2.25.1"

{ cis'' \ottava 1 cis''' }
