Yes, this is known behaviour. Here is the workaround I use:

First you define the follwing function:

forget = #(define-music-function (parser location music) (ly:music?) #{
        #(set-accidental-style 'forget)
        $music
        #(set-accidental-style 'modern)
#})


And then, you use it in front of the note which you do not want the
sharp of flat in front of:

\repeat { c } \alternative { { cis } { \forget c } }
