Hello. I want to engrave this sheet music.

%% all notes change one octave up after a half rest

\score {
        \relative e'' {
                \key e \major   
                e2 fis4 (gis)
                fis2 gis4 (a)
                gis2 a4 (b)
                a4 (gis) a (fis)
                e2 fis4 (gis)
                fis2 gis4 (a)
                gis2 a4 (fis)
                b2 r2
                e,2 fis4 (gis)
                
        }
        
        \layout { }
        
        \midi { }
}

May you pay attention to the measure second to last. There is a half rest there.
I have to use a , to change correctly engrave the last measure. If i don't use a
, like e2 fis4 (gis) all notes change one octave up. Or if i don't use a half
rest in the measure second to last (like b2 a2) all things work as it should be.
I am quite new to lilypond so this may be a user error. But if it is a bug i
want to warn about this issue.
