'Display Marked Drawings in the Onion Skin" only in drawing view?


in testing harmony’s toolbars to “display marked drawings in onion skin”, i can only get it to function in the drawing view, is that correct?
in camera view, with the same selections on the same toolbars, my tests show no difference if the ‘show key drawings’ button is selected or not; i still see all the in-betweens.
but in drawing view i correctly see only my keys.

anything i’m missing?

the reason i ask, is that transformations only show in camera view, correct? so if i’m re-working drawings based where they are transformed on screen, i can’t use the ‘display marked drawings’.
